• gpfs_images_dir | string

  Specifies the path of the Image service repository in GPFS. Leave undefined if not storing images in GPFS.

• gpfs_images_share_mode | string

  Specifies the type of image copy to be used. Set this when the Image service repository also uses GPFS so that image files can be transferred efficiently from the Image service to the Block Storage service. There are two valid values: "copy" specifies that a full copy of the image is made; "copy_on_write" specifies that copy-on-write optimization strategy is used and unmodified blocks of the image file are shared efficiently.

• gpfs_mount_point_base | string

  Specifies the path of the GPFS directory where Block Storage volume and snapshot files are stored.

• gpfs_private_key | string

  Default: /var/lib/cinder/id_rsa

  Filename of private key to use for SSH authentication

• gpfs_sparse_volumes | boolean

  Default: True

  Specifies that volumes are created as sparse files which initially consume no space. If set to False, the volume is created as a fully allocated file, in which case, creation may take a significantly longer time.

• gpfs_ssh_port | int

  Default: 22

  SSH port to use

• gpfs_storage_pool | string

  Default: system

  Specifies the storage pool that volumes are assigned to. By default, the system storage pool is used.

• gpfs_user_login | string

  Default: root

  Username for GPFS nodes

• volume-driver | string

  Default: cinder.volume.drivers.ibm.gpfs.GPFSRemoteDriver

  This value denotes the volume driver value.
