The cinder.volume.drivers.falconstor.fss_common Module

The cinder.volume.drivers.falconstor.fss_common Module

Volume driver for FalconStor FSS storage system.

This driver requires FSS-8.00-8865 or later.

class FalconstorBaseDriver(*args, **kwargs)

Bases: cinder.volume.drivers.san.san.SanDriver

attach_volume(context, volume, instance_uuid, host_name, mountpoint)
check_for_setup_error()
create_cgsnapshot(context, cgsnapshot, snapshots)

Creates a cgsnapshot.

create_cloned_volume(volume, src_vref)

Creates a clone of the specified volume.

create_consistencygroup(context, group)

Creates a consistencygroup.

create_export(context, volume, connector)
create_snapshot(snapshot)

Creates a snapshot.

create_volume(volume)

Creates a volume.

We use the metadata of the volume to create variety volume.

Create a thin provisioned volume :

create --volume-type FSS-THIN
    --metadata thinsize=<thin-volume-size> volume-size

Create a LUN that is a Timeview of another LUN at a specified CDP tag:

create --volume-type FSS --metadata timeview=<vid>
    cdptag=<tag> volume-size

Create a LUN that is a Timeview of another LUN at a specified Timemark:

create --volume-type FSS --metadata timeview=<vid>
    rawtimestamp=<rawtimestamp> volume-size

Create a mirrored volume :

create --volume-type FSS --metadata mirrored=true
create_volume_from_snapshot(volume, snapshot)

Creates a volume from a snapshot.

delete_cgsnapshot(context, cgsnapshot, snapshots)

Deletes a cgsnapshot.

delete_consistencygroup(context, group, volumes)

Deletes a consistency group.

delete_snapshot(snapshot)

Deletes a snapshot.

delete_volume(volume)

Disconnect all hosts and delete the volume

detach_volume(context, volume, attachment=None)
do_setup(context)
ensure_export(context, volume)
extend_volume(volume, new_size)

Extend volume to new_size.

get_volume_stats(refresh=False)
manage_existing(volume, existing_ref)

Convert an existing FSS volume to a Cinder volume.

We expect a volume id in the existing_ref that matches one in FSS.

manage_existing_get_size(volume, existing_ref)

Get size of an existing FSS volume.

We expect a volume id in the existing_ref that matches one in FSS.

remove_export(context, volume)
unmanage(volume)

Remove Cinder management from FSS volume

update_consistencygroup(context, group, add_volumes=None, remove_volumes=None)
