Scality SOFS driver

The Scality SOFS volume driver interacts with configured sfused mounts.

The Scality SOFS driver manages volumes as sparse files stored on a Scality Ring through sfused. Ring connection settings and sfused options are defined in the cinder.conf file and the configuration file pointed to by the scality_sofs_config option, typically /etc/sfused.conf.

Supported operations

The Scality SOFS volume driver provides the following Block Storage volume operations:

  • Create, delete, attach (map), and detach (unmap) volumes.
  • Create, list, and delete volume snapshots.
  • Create a volume from a snapshot.
  • Copy an image to a volume.
  • Copy a volume to an image.
  • Clone a volume.
  • Extend a volume.
  • Backup a volume.
  • Restore backup to new or existing volume.

Configuration

Use the following instructions to update the cinder.conf configuration file:

[DEFAULT]
enabled_backends = scality-1

[scality-1]
volume_driver = cinder.volume.drivers.scality.ScalityDriver
volume_backend_name = scality-1

scality_sofs_config = /etc/sfused.conf
scality_sofs_mount_point = /cinder
scality_sofs_volume_dir = cinder/volumes

Compute configuration

Use the following instructions to update the nova.conf configuration file:

[libvirt]
scality_sofs_mount_point = /cinder
scality_sofs_config = /etc/sfused.conf
