Storage Tab¶
The Storage tab on the Host Detail page presents storage details for a host.
The information is presented in one or more lists, as determined by the host type.
Disks¶
This list is presented for all host types. It lists all available hardware devices used for storage.
For each device, the following information is included:
- UUID
The unique identifier for the device.
- Disk Info
The Linux device path.
- Type
The type of storage device (HDD or SSD).
- Size
The capacity of the device in MiB.
- Available Size
The space available for partitioning.
- RPM
The rotational speed of the device.
- Serial ID
The device’s serial ID number.
- Model
The manufacturer’s model for the device.
Partitions¶
For all host types, this list shows user-created disk partitions.
- UUID
The unique identifier for the device.
- Partition Device Path
The Linux device path.
- Size
The capacity of the partition in MiB.
- Partition Type
The storage backing and the partition type, such as physical or logical.
- Status
The usage status, such as Creating, Ready, Deleting, or In-use.
- Actions
Controls for editing or deleting a partition, if it is not currently in use.
Physical Volumes¶
On controller and worker hosts, this list shows physical volumes (disk or partitions) assigned to local volume groups.
- Name
The Linux device name associated with the physical volume.
- State
The availability of the physical volume.
- Type
The device type used for the physical volume.
- Disk or Partition UUID
The unique identifier for the disk or partition used to implement the physical volume.
- Disk or Partition Device Path
The device used to implement the physical volume, identified by path.
- LVM Volume Group name
The name of the local volume group to which the physical volume belongs.
- Actions
Available actions that can be performed on the physical volume.
Storage Functions¶
This list is presented for storage hosts. It shows a list of logical storage functions (OSDs and Ceph journal functions) defined on available disks.
For each volume, the following information is included:
- UUID
The unique identifier for the storage volume.
- Function
The type of function (osd for object storage, or journal for Ceph journal storage).
- OSD ID
For an OSD function, the identity of the associated Ceph object storage daemon.
- Disk UUID
The unique identifier for the disk associated with the storage volume.
- Journal Path
For an OSD function, the path to the device where the associated Ceph journal is maintained.
- Journal GiB
For an OSD function, the size of the associated Ceph journal.
- Journal Location
For an OSD function, the unique identifier for the associated journal function, if applicable.
