Zed Series (20.2.0 - 21.1.x) Release Notes

21.1.2-10

Upgrade Notes

• When upgrading Ironic to address the qemu-img image conversion security issues, the ironic-python-agent ramdisks will also need to be upgraded.

• As a result of security fixes to address qemu-img image conversion security issues, a new configuration parameter has been added to Ironic, [conductor]permitted_image_formats with a default value of “raw,qcow2,iso”. Raw and qcow2 format disk images are the image formats the Ironic community has consistently stated as what is supported and expected for use with Ironic. These formats also match the formats which the Ironic community tests. Operators who leverage other disk image formats, may need to modify this setting further.

Security Issues

• Ironic now checks the supplied image format value against the detected format of the image file, and will prevent deployments should the values mismatch. If being used with Glance and a mismatch in metadata is identified, it will require images to be re-uploaded with a new image ID to represent corrected metadata. This is the result of CVE-2024-44082 tracked as bug 2071740.

• Ironic always inspects the supplied user image content for safety prior to deployment of a node should the image pass through the conductor, even if the image is supplied in raw format. This is utilized to identify the format of the image and the overall safety of the image, such that source images with unknown or unsafe feature usage are explicitly rejected. This can be disabled by setting [conductor]disable_deep_image_inspection to True. This is the result of CVE-2024-44082 tracked as bug 2071740.

• Ironic also inspect images which would normally be provided as a URL for direct download by the ironic-python-agent ramdisk. This is enabled by default and increases the overall network traffic and disk space utilization of the conductor. This level of inspection can be disabled by setting [conductor]conductor_always_validates_images to False. Doing so is not advisable as Zed release and earlier ironic-python-agent ramdisks will not be made available due to backport regression risk. This is the result of CVE-2024-44082 tracked as bug 2071740.

• Ironic now explicitly enforces a list of permitted image types for deployment via the [conductor]permitted_image_formats setting, which defaults to “raw”, “qcow2”, and “iso”. While the project has classically always declared permissible images as “qcow2” and “raw”, it was previously possible to supply other image formats known to qemu-img, and the utility would attempt to convert the images. The “iso” support is required for “boot from ISO” ramdisk support.

• Ironic now explicitly passes the source input format to executions of qemu-img to limit the permitted qemu disk image drivers which may evaluate an image to prevent any mismatched format attacks against qemu-img.

• The ansible deploy interface example playbooks now supply an input format to execution of qemu-img. If you are using customized playbooks, please add “-f {{ ironic.image.disk_format }}” to your invocations of qemu-img. If you do not do so, qemu-img will automatically try and guess which can lead to known security issues with the incorrect source format driver.

• Operators who have implemented any custom deployment drivers or additional functionality like machine snapshot, should review their downstream code to ensure they are properly invoking qemu-img. If there are any questions or concerns, please reach out to the Ironic project developers.

• Operators are reminded that they should utilize cleaning in their environments. Disabling any security features such as cleaning or image inspection are at your own risk. Should you have any issues with security related features, please don’t hesitate to open a bug with the project.

• The [conductor]disable_deep_image_inspection setting is conveyed to the ironic-python-agent ramdisks automatically, and will prevent those operating ramdisks from performing deep inspection of images before they are written.

• The [conductor]permitted_image_formats setting is conveyed to the ironic-python-agent ramdisks automatically. Should a need arise to explicitly permit an additional format, that should take place in the Ironic service configuration.

• An issue in Ironic has been resolved where image checksums would not be checked prior to the conversion of an image to a raw format image from another image format.

  With default settings, this normally would not take place, however the image_download_source option, which is available to be set at a node level for a single deployment, by default for that baremetal node in all cases, or via the [agent]image_download_source configuration option when set to local. By default, this setting is http.

  This was in concert with the [DEFAULT]force_raw_images when set to True, which caused Ironic to download and convert the file.

  In a fully integrated context of Ironic’s use in a larger OpenStack deployment, where images are coming from the Glance image service, the previous pattern was not problematic. The overall issue was introduced as a result of the capability to supply, cache, and convert a disk image provided as a URL by an authenticated user.

  Ironic will now validate the user supplied checksum prior to image conversion on the conductor. This can be disabled using the [conductor]disable_file_checksum configuration option.

• Fixes OSSA-2025-001, where Ironic did not properly filter file:// paths when used as image sources. This would permit any file accessible by the conductor to be used as an image to attempt deployment.

  Adds CONF.conductor.file_url_allowed_paths, an allowlist configuration defaulting to /var/lib/ironic, /shared/html, /opt/cache/files, /vagrant, and /templates, permits operators to further restrict where the conductor will fetch images for when provided a file:// URL. This default value was chosen based on known usage by projects downstream of Ironic, including Metal3, Bifrost, and OpenShift. These defaults may change to be more restrictive at a later date. Operators using file:// URLs are encouraged to explicitly set this value even if the current default is sufficient. Operators wishing to fully disable the ability to deploy with a file:// URL should set this configuration to “” (empty).

  Operators wishing to restore the original insecure behavior should set CONF.conductor.file_url_allowed_paths to /. Take note that in the 2025.2 release and later, /dev, /sys, /proc, /run, and /etc will be unconditionally blocked as a security measure.

  This issue only poses a significant security risk when Ironic’s automated cleaning process is disabled and the service is configured in such a way that permits direct deployment by an untrusted API user, such as standalone Ironic installations or environments granting ownership of nodes to projects.

Bug Fixes

• Fixes multiple issues in the handling of images as it relates to the execution of the qemu-img utility, which is used for image format conversion, where a malicious user could craft a disk image to potentially extract information from an ironic-conductor process’s operating environment.

  Ironic now explicitly enforces a list of approved image formats as a [conductor]permitted_image_formats list, which mirrors the image formats the Ironic project has historically tested and expressed as known working. Testing is not based upon file extension, but upon content fingerprinting of the disk image files. This is tracked as CVE-2024-44082 via bug 2071740.

• Fixes a security issue where Ironic would fail to checksum disk image files it downloads when Ironic had been requested to download and convert the image to a raw image format. This required the image_download_source to be explicitly set to local, which is not the default.

  This fix can be disabled by setting [conductor]disable_file_checksum to True, however this option will be removed in new major Ironic releases.

  As a result of this, parity has been introduced to align Ironic to Ironic-Python-Agent’s support for checksums used by standalone users of Ironic. This includes support for remote checksum files to be supplied by URL, in order to prevent breaking existing users which may have inadvertently been leveraging the prior code path. This support can be disabled by setting [conductor]disable_support_for_checksum_files to True.

• The fix for CVE-2024-47211 results in image checksum being required in all cases. However there is no checksum requirement for file:// based images. When checksum is missing for file:// based image_source it is now calculated on-the-fly.

21.1.2

Upgrade Notes

• Adds sha256, sha384 and sha512 as supported SNMPv3 authentication protocols to iRMC driver.

• ipxe boot_interface will be preferred to irmc-pxe by default with the irmc hardware type during the new baremetal node creation. This change doesn’t affect to the existing baremetal nodes. Operators who want to continue to use irmc-pxe as default boot interface need to specify it in [DEFAULT]default_boot_interface setting in ironic.conf.

Bug Fixes

• Fixes bug in iRMC driver, where irmc power_interface sets and updates irmc_ipmi_succeed flag which is used by rest of iRMC driver code to deal with iRMC firmware’s IPMI incompatibility but ipmitool power_interface doesn’t set nor update irmc_ipmi_succeed flag and rest of iRMC driver code fail to handle iRMC firmware’s IPMI incompatibility correctly.

• Fixes an issue where a System Scoped user could not trigger a node into a manageable state with cleaning enabled, as the Neutron client would attempt to utilize their user’s token to create the Neutron port for the cleaning operation, as designed. This is because with requests made in the system scope, there is no associated project and the request fails.

  Ironic now checks if the request has been made with a system scope, and if so it utilizes the internal credential configuration to communicate with Neutron.

• Fixes the default boot interface order for the irmc hardware type where previously it would prefer irmc-pxe over ipxe. This created inconsistencies for operators using multiple hardware types, where both interfaces were enabled in the deployment. Because the fix is backported on this point of releasae of Zed, operators who will update their environment beyond this release have to check the related upgrade note and take necessary action even though their update will be done in Zed release.

• Fixes issues with Lenovo hardware where the system firmware may display a blue “Boot Option Restoration” screen after the agent writes an image to the host in UEFI boot mode, requiring manual intervention before the deployed node boots. This issue is rooted in multiple changes being made to the underlying NVRAM configuration of the node. Lenovo engineers have suggested to only change the UEFI NVRAM and not perform any further changes via the BMC to configure the next boot. Ironic now does such on Lenovo hardware. More information and background on this issue can be discovered in bug 2053064.

21.1.1

Upgrade Notes

• When Ironic operator uses irmc driver against Fujitsu server which runs iRMC version S6 2.00 or later, operator may need to set Redfish parameters in driver_info so this fix can operate properly or operator should enable IPMI over LAN through BMC settings, if possible.

Bug Fixes

• Fixes Ironic integration with Cinder because of changes which resulted as part of the recent Security related fix in bug 2004555. The work in Ironic to track this fix was logged in bug 2019892. Ironic now sends a service token to Cinder, which allows for access restrictions added as part of the original CVE-2023-2088 fix to be appropriately bypassed. Ironic was not vulnerable, but the restrictions added as a result did impact Ironic’s usage. This is because Ironic volume attachments are not on a shared “compute node”, but instead mapped to the physical machines and Ironic handles the attachment life-cycle after initial attachment.

• When aborting cleaning, the last_error field is no longer initially empty. It is now populated on the state transition to clean failed.

• When cleaning or deployment fails, the last_error field is no longer temporary set to None while the power off action is running.

• Fixes Invalid cross-device link in some cases when using file:// image URLs.

• Fixes an issue where if selinux is enabled and enforcing, and the published image is a hardlink, the source selinux context is preserved, causing access denied when retrieving the image using hardlink URL.

• Fixes bug of iRMC driver in parse_driver_info where, if FIPS is enabled, SNMP version is always required to be version 3 even though iRMC driver’s xxx_interface doesn’t use SNMP actually.

• Fixes a firmware incompatibility issue with iRMC versions S6 2.00 and later now doesn’t support IPMI over LAN by default. To deal with this problem, irmc driver first tries IPMI operation then, if IPMI operation fails, it tries Redfish API of Fujitsu server. The operator must set Redfish parameters in the driver_info if iRMC disable or doesn’t support IPMI over LAN.

• Fixes 'NoneType' object is not iterable in conductor logs for redfish and idrac-redfish RAID clean and deploy steps. The message should no longer appear. For affected nodes re-create the node or delete raid_configs entry from driver_internal_info field.

• Fixes an issue in the online upgrade logic where database models for Node Traits and BIOS Settings resulted in an error when performing the online data migration. This was because these tables were originally created as extensions of the Nodes database table, and the schema of the database was slightly different enough to result in an error if there was data to migrate in these tables upon upgrade, which would have occured if an early BIOS Setting adopter had data in the database prior to upgrading to the Yoga release of Ironic.

  The online upgrade parameter now subsitutes an alternate primary key name name when applicable.

• Fixes an issue where an agent token could be inadvertently orphaned if a node is already in the target power state when we attempt to turn the node off.

• Fixes scope classification check with the “self_owned_node” policy check where it was limited to check execution with only project scoped, so system scoped users who ticked the policy endpoint would basically get an incorrect error.

• Fixes the bug where provisioning a Redfish managed node fails if the BMC doesn’t support EthernetInterfaces attribute, even if MAC address information is provided manually. This is done by handling of MissingAttributeError sushy exception in get_mac_addresses() method. This fix is needed to successfully provision machines such as Cisco UCSB and UCSX.

• Modify iRMC driver to use ironic.conf [deploy] default_boot_mode to determine default boot_mode.

• No longer re-calculates checksums for images that are already raw. Previously, it would cause significant delays in deploying raw images.

• The per-node external_http_url setting in the driver info is now used for a boot ISO. Previously this setting was only used for a config floppy.

• Fixes an issue where an agent token was being orphaned if a baremetal node timed out during cleaning operations, leading to issues where the node would not be able to establish a new token with Ironic upon future in some cases. We now always wipe the token in this case.

21.1.0

Prelude

The Ironic team hereby announces the release of the Zed version of Ironic. This version, 21.1.0, represents the collaboration of Ironic’s contributors during the Zed release cycle, which first saw the release of Ironic 20.2.0, and Ironic 21.1.0. These versions saw improvements in functionality to better support infrastructure operators from the configuration of individual nodes, to support a greater separation of duties, and ultimately Self-Service Bare Metal as a Service, or “SSBMaaS”. Along with these features, these releases have seen numerous bug fixes. We sincerely hope you enjoy it!

New Features

• Adds raritan_pdu2, servertech_sentry3, servertech_sentry4, and vertivgest_pdu snmp drivers to support additional PDU models.

• Adds an automatic switch to url for the kickstart template when the source is a URL path as opposed to a stage2 ramdisk.

• Adds a concurrency limiter for number of nodes in states related to Cleaning and Provisioning operations across the ironic deployment. These settings default to a maximum number of concurrent deployments to 250 and a maximum number of concurrent deletes and cleaning operations to 50. These settings can be tuned using [conductor]max_concurrent_deploy and [conductor]max_concurrent_clean, respectively. The defaults should generally be good for most operators in most cases. Large scale operators should evaluate the defaults and tune appropriately as this feature cannot be disabled, as it is a security mechanism.

• Adds new clean steps create_csr and add_https_certificate to ilo and ilo5 hardware types which allows users to create Certificate Signing Request(CSR) and adds signed HTTPS certificate to the iLO.

• The [dhcp]dhcp_provider configuration option can now be set to dnsmasq as an alternative to none for standalone deployments. This enables the same node-specific DHCP capabilities as the neutron provider. See the [dnsmasq] section for configuration options.

• Provides vendor passthru methods for ilo and ilo5 hardware types to create, delete and get subscriptions for BMC events. These methods are supported for HPE ProLiant Gen10 and HPE ProLiant Gen10 Plus servers.

• Adds the capability for a project scoped admin user to be able to create nodes in Ironic, which are then manageable by the project scoped admin user. Effectively, this is self service Bare Metal as a Service, however more advanced fields such as drivers, chassies, are not available to these users. This is controlled through an auto-population of the Node owner field, and can be controlled through the [api]project_admin_can_manage_own_nodes setting, which defaults to True, and the new policy baremetal:node:create:self_owned_node.

• Adds the capability for a project scoped admin user to be able to delete nodes from Ironic which their project owns. This can be contolled through the [api]project_admin_can_manage_own_nodes setting, which defaults to True, as well as the baremetal:node:delete:self_owned_node policy.

Upgrade Notes

• Large scale operators should be aware that a new feature, referred to as “Concurrent Action Limit” was introduced as a security mechanism to provide a means to limit attackers, or faulty scripts, from potentially causing irreperable harm to an environment. This feature cannot be disabled, and operators are encouraged to tune the new settings [conductor]max_concurrent_deploy and [conductor]max_concurrent_clean to match the needs of their environment.

• Operators who are upgrading should be aware that a bug was discovered with the automatic selection of boot_interface for users of the ilo and ilo5 hardware types. This was an inconsistency, resulting in pxe being selected instead of ipxe if both boot interfaces were enabled. Depending on the local configuration, this may, or may not have happened and will remain static on preexisting baremetal nodes. Some users may have been relying upon this incorrect behavior by having misalligned defaults by trying to use the pxe interface for ipxe. Users wishing to continue this usage as it was previously will need to explicitly set a boot_interface value to either pxe or ilo-ipxe by default, depending on the local configuration. Most operators have leveraged the default examples, and thus did not explicitly encounter this condition. Operators explicitly wishing to use pxe boot interfaces with the ipxe templates and defaults set to override the defaults for ironic.conf will need to either continue to leverage default override configurations in their ironic.conf file.

Security Issues

• This release contains an improvement which, by default, allows users to create and delete baremetal nodes inside their own project. This can be disabled using the [api]project_admin_can_manage_own_nodes setting.

Bug Fixes

• Fixes detecting of allowable values for a BIOS settings enumeration in the redfish BIOS interface when only ValueDisplayName is provided.

• Adds a configuration option, [anaconda]insecure_heartbeat to allow for TLS certificate validation to be disabled in the anaconda deployment interface, which is needed for continious integration to be able to be performed without substantial substrate image customization. This option is not advised for any production usage.

• Fixes an issue where image information retrieval would fail when a path was supplied when using the anaconda deploy interface, as HTTP HEAD requests on a URL path have no Content-Length. We now consider if a path is used prior to attempting to collect additional configuration data from what is normally expected to be Glance.

• Fixes an issue where the fallback to a default kickstart template value would result in error indicating “Scheme-less image href is not a UUID”. This was becaues the handling code falling back to the default did not explicitly indicate it was a file URL before saving the value.

• Fixes an issue where cleaning operations could fail in such a way that was not easily recoverable when pre-cleaning network interface configuration was validated, yet contained invalid configuration. Now Ironic properly captures the error and exits from cleaning in a state which allows for cleaning to be retried.

• Fixes idrac-redfish RAID delete_configuration step to convert PERC 9 and PERC 10 controllers to RAID mode if it is not already set.

• Fixes the default boot interface order for the ilo hardware type where previously it would prefer pxe over ipxe. This created inconsistencies for operators using multiple hardware types, where both interfaces were enabled in the deployment.

• Fixes API error messages with jsonschema>=4.8. A possible root cause is now detected for generic schema errors.

• Fixes an issue where the Redfish session cache would continue using an old session when a password for a Redfish BMC was changed. Now the old session will not be found in this case, and a new session will be created with the latest credential information available.

Other Notes

• The maximum disk erasure concurrency setting, [deploy]disk_erasure_concurrency has been incremed to 4. Previously, this was kept at 1 in order to maintain continuity of experience, but operators have not reported any issues with an increased concurrency, and as such we feel comfortable upstream enabling concurrent disk erasure/cleaning. This setting applies to the erase_devices clean step.

21.0.0

New Features

• Adds a new feature to permit Ironic to automatically provide an instance requestor’s project, lessee rights to the Bare Metal machine under the Role Based Access Control model implemented in Ironic. It does this by saving the project ID of the requestor to the Node lessee field automatically, and removing the rights when undeploying the machine. This feature, is normally disabled, but can be enabled using the [conductor]automatic_lessee configuration option. This option will not work in a mixed-version upgrade with older API services.

• Adds a default project scoped manager role to the RBAC model. In the ironic model, access is generally explicitly delegated, and such the manager role is presently equivelent to project scoped admin role, however future delineation may occur as the new features and capabilities are added.

• When an allocation is being processed, the randomized candidate list is now modified so that a node with a matching name to the allocation is moved to the beginning of the list. This greatly increases the chance of node name and allocation name matching in environments where the naming schemes align.

• Adds driver_info/irmc_verify_ca option to specify certification file. Default value of driver_info/irmc_verify_ca is True.

• Adds SNMPv3 message authentication and encryption features to iRMC driver. To enable these features, the following parameters should be used in the node’s driver_info:

  • irmc_snmp_user

  • irmc_snmp_auth_password

  • irmc_snmp_priv_password

  • irmc_snmp_auth_proto (Optional, defaults to sha)

  • irmc_snmp_priv_proto (Optional, defaults to aes)

  irmc_snmp_auth_proto and irmc_snmp_priv_proto can also be set through the following options in the [irmc] section of /etc/ironic/ironic.conf:

  • snmp_auth_proto

  • snmp_priv_proto

• Nodes using virtual media can now specify their own external URL. This setting can be leveraged via the driver_info\external_http_url node setting. When used, this setting overrides the [deploy]http_url and [deploy]external_http_url settings in the configuration file.

• The ramdisk deploy interface is now enabled by default. When the default direct deploy is also enabled, the ramdisk deploy must be explicitly requested on the node level.

Known Issues

• When using jsonschema 4.0.0 or newer, make sure to include a proper $schema field in your custom network data or RAID schemas.

Upgrade Notes

• The deprecated support for instance network booting (not to be confused with the ramdisk deploy, iSCSI boot or Anaconda deploy) has been removed. The boot_option capability is no longer supported.

• Support for trusted boot has been removed. This feature requires instance network booting, which is also removed this cycle.

Deprecation Notes

• Support for the syslinux and the often separately package isolinux and pxelinux. Legacy BIOS boot loaders, is deprecated and will be removed the future. This is for two reasons. The first is because it is a BIOS mode bootloader, and the shift to UEFI booting has reduced the need for these packages. The second reason is a lack of maintenance, which is ultimately the same reason Linux distributions are discussing dropping support and packaging. Syslinux has not been updated since 2019. Incidently, the file format it utilizes is supported by Power hardware, and that may result in the configuration template remaining in Ironic for the forseeable future.

• Support for use of pxelinux is deprecated due to the deprecation of support for Syslinux.

• Support for virtual media booting with x86 Hardware in Legacy BIOS mode is deprecated due to the dependency upon isolinux for use of Legacy BIOS boot mode. isolinux is from the syslinux package and source tree.

• Deprecation of pxelinux, as a result of the deprecation of syslinux, does ultimately mean the default for the pxe boot_interface to carry defaults for the use of grub based network booting, specifically for operators who are unable to use iPXE.

• Deprecates the irmc_snmp_security field in driver_info for iRMC driver, it will be removed in the future. Please use irmc_snmp_user field instead.

Security Issues

• Modifies the irmc hardware type to include a capability to control enforcement of HTTPS certificate verification. By default this is enforced. python-scciclient >= 0.12.0 is required.

Bug Fixes

• Fixes an issue where root_gb became a required field when using the anaconda deployment interface, with a recent bug fix as the code path largely expected all deployment operations to utilize images, which is not the case. The case handling for non-image based deployments is now explicitly in internal parameter validation code.

• Fixes handling of image_source parameters where internal validations would not gracefully handle received redirects and treat it as a failure. We now no longer explicitly fail when a redirect is received.

• Fixes an issue where an image_source could not be set to a mirror URL to facilitate deployments using a mirror with the anaconda deployment interface. Ironic still presently has an explicit requirement on a stage2 parameter to be explicitly defined.

• Fixes rebooting into the agent after changing BIOS settings in fast-track mode with the redfish-virtual-media boot interface. Previously, the ISO would not be configured.

• Fixes OSError: [Errno 36] File name too long when building a virtual media ISO from a long kernel, ramdisk or ESP URL.

• Fixes an issue in the anaconda deployment interface where PXE argument processing and preparation was erroneously directly connecting to Glance, potentially leading to an exception in the standalone use case.

• Fixes redfish and idrac-redfish RAID create_configuration, apply_configuration, delete_configuration clean and deploy steps to update node’s raid_config field at the end of the steps.

• Fixes redfish-virtual-media boot interface to allow it with iDRAC firmware from 6.00.00.00 (released June 2022) as it has virtual media boot issue fixed that prevented iDRAC firmware to work with redfish-virtual-media before. Consider upgrading iDRAC firmware if not done already, otherwise will still get an error when trying to use redfish-virtual-media with iDRAC.

• Fixes compatibility with jsonschema package version 4.0.0 or newer by providing a proper schema version (Draft-07 currently).

• Fixes a race condition in PXE initialization where the logic to retry what we suspect as potentially failed PXE boot operations was not consulting if an agent token had been established, which is the very first step in agent initialization.

• When the ramdisk deploy interface is used and automated cleaning is disabled, the pxe, ipxe and redfish-virtual-media boot interfaces no longer require a deploy kernel/ramdisk to be provided.

• Anaconda supports the ability to explicitly pass a URL instead of a stage2 ramdisk parameter. This has resulted in confusion in use of the anaconda deployment interface, as a stage2 ramdisk is typically not used, but made sense with Glance images in a fully integrated OpenStack deployment. Now a URL to a path can be supplied to the anaconda deployment interface to simplify the interaction and use, and a redundant stage2 parameter is no longer required.

• Resolved clear_job_queue and reset_idrac verify step failures which occur when the functionality is not supported by the iDRAC. When this condition is detected, the code in the step handles the exception and logs a warning and completes successfully in case of verification steps but fails in case of cleaning steps.

• Fixes an issue where an API user, when requesting a node list or single node object, could get an error indicating that the request was bad as the chassis was not found. This can occur when in-flight delete operations are in progress on another thread. Instead of surfacing a request breaking error, the API now suppresses the error and just treats it as if there is no Chassis.

• Fixes enable_netboot_fallback to cause iPXE config to exit 0 when “sanboot –no-describe” fails. Allowing the firmware to move onto the next device in the boot order.

Other Notes

• Adds documentation of standalone deployment use case with the anaconda deployment interface.

• Updates the minimum version of python-scciclient library to 0.12.1.

• Known issue when using iDRAC with Swift to stage firmware update files in Management interface firmware_update clean step of redfish or idrac hardware type has been fixed in iDRAC firmware 6.00.00.00. Upgrade when possible or use HTTP service to stage firmware files for iDRAC.

20.2.0

New Features

• When using per-node kernel parameters, i.e. kernel_append_params in the node’s instance_info or driver_info, it is now possible to insert the value of the driver’s configuration option (e.g. [pxe]kernel_append_params via the special %default% syntax, e.g.:

  baremetal node set node-0 \
    --driver-info kernel_append_params="%default% foo=bar"
  

Bug Fixes

• The combined ironic executable now starts the API only after the built-in conductor starts. This avoids error 500 on requests while the conductor is starting.

• Fixes an issue where a conductor would attempt local takeover. In case of heartbeat failure due to resource starvation, the current conductor was detected as offline when querying the database. In this scenario the conductor would forcibly remove reservations of it’s own and initiate takeover. Current conductor is now excluded from the list of offline conductors, so that local takeover does not occur for this case. A warning is logged to highlight the potential resource starvation issue. See bug: 2010016.

• Fix a bug when configuring RAID caused by not converting the port value to int type when the node managed by the irmc hardware type.
