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.

CI_WIKI_NAME = ‘Cinder_Jenkins’¶

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’¶

extend_volume(volume, new_size)¶

is_clean_volume_name(name, prefix)¶

local_path(volume)¶

snapshot_name_from_cinder_snapshot(snapshot)¶

class DrbdManageDrbdDriver(*args, **kwargs)¶

Bases: cinder.volume.drivers.drbdmanagedrv.DrbdManageBaseDriver

Cinder driver that uses the DRBD protocol.

create_export(context, volume, connector)¶

ensure_export(context, volume)¶

get_volume_stats(refresh=False)¶

Get volume status.

initialize_connection(volume, connector)¶

remove_export(context, volume)¶

terminate_connection(volume, connector, force=False, **kwargs)¶

DrbdManageDriver¶

alias of DrbdManageIscsiDriver

class DrbdManageIscsiDriver(*args, **kwargs)¶

Bases: cinder.volume.drivers.drbdmanagedrv.DrbdManageBaseDriver

Cinder driver that uses the iSCSI protocol.

create_export(context, volume, connector)¶

ensure_export(context, volume)¶

get_volume_stats(refresh=False)¶

Get volume status.

initialize_connection(volume, connector)¶

remove_export(context, volume)¶

terminate_connection(volume, connector, **kwargs)¶

validate_connector(connector)¶
