The cinder.volume.drivers.ibm.ibmnas Module

IBM NAS Volume Driver. Currently, it supports the following IBM Storage Systems: 1. IBM Scale Out NAS (SONAS) 2. IBM Storwize V7000 Unified 3. NAS based IBM GPFS Storage Systems

Notes: 1. If you specify both a password and a key file, this driver will use the

key file only.
  1. When using a key file for authentication, it is up to the user or system administrator to store the private key in a safe manner.
class IBMNAS_NFSDriver(execute=<function execute>, *args, **kwargs)

Bases: cinder.volume.drivers.nfs.NfsDriver, cinder.volume.drivers.san.san.SanDriver

Creates file on NFS share for using it as block device on hypervisor. Version history: 1.0.0 - Initial driver 1.1.0 - Support for NFS based GPFS storage backend

VERSION = '1.1.0'
check_for_setup_error()

Ensure that the flags are set properly.

create_cloned_volume(volume, src_vref)

Extends the volume if the new volume size is more than the source volume size.

create_snapshot(snapshot)

Creates a volume snapshot.

create_volume_from_snapshot(volume, snapshot)

Creates a volume from an existing volume snapshot.

Extends the volume if the volume size is more than the snapshot size.

delete_snapshot(snapshot)

Deletes a volume snapshot.

delete_volume(volume)

Deletes a logical volume.

do_setup(context)

Any initialization the volume driver does while starting.

driver_volume_type = 'nfs'
extend_volume(volume, new_size)

Extend an existing volume to the new size.
