The cinder.volume.drivers.drbdmanagedrv Module

This driver connects Cinder to an installed DRBDmanage instance, see

http://drbd.linbit.com/users-guide-9.0/ch-openstack.html

for more details.

class DrbdManageBaseDriver(*args, **kwargs)

Bases: cinder.volume.driver.VolumeDriver

Cinder driver that uses DRBDmanage for storage.

VERSION = '1.1.0'

call_or_reconnect(fn, *args)

Call DBUS function; on a disconnect try once to reconnect.

check_for_setup_error()

Verify that requirements are in place to use DRBDmanage driver.

create_cloned_volume(volume, src_vref)

create_snapshot(snapshot)

Creates a snapshot.

create_volume(volume)

Creates a DRBD resource.

We address it later on via the ID that gets stored as a private property.

create_volume_from_snapshot(volume, snapshot)

Creates a volume from a snapshot.

dbus_connect()

delete_snapshot(snapshot)

Deletes a snapshot.

delete_volume(volume)

Deletes a resource.

do_setup(context)

Any initialization the volume driver does while starting.

drbdmanage_dbus_interface = '/interface'

drbdmanage_dbus_name = 'org.drbd.drbdmanaged'

class DrbdManageDrbdDriver(*args, **kwargs)

Bases: cinder.volume.drivers.drbdmanagedrv.DrbdManageBaseDriver

Cinder driver that uses the DRBD protocol.

ensure_export(context, volume)

get_volume_stats(refresh=False)

Get volume status.

initialize_connection(volume, connector)

remove_export(context, volume)

DrbdManageDriver

alias of DrbdManageIscsiDriver

class DrbdManageIscsiDriver(*args, **kwargs)

Bases: cinder.volume.drivers.drbdmanagedrv.DrbdManageBaseDriver
