grizzly: cinder nfs driver is undocumented

[Tom Fifield]

Grizzly introduces an NFS driver for Cinder. There is currently no documentation regarding this.

The code can be found in the cinder repository at /cinder/volume/drivers/nfs.py

Here are some options:

34 cfg.StrOpt('nfs_mount_point_base',
 35 35 default='$state_path/mnt',
 36 36 help='Base dir where nfs expected to be mounted'),
 37 37 cfg.StrOpt('nfs_disk_util',
 38 38 default='df',
 39 39 help='Use du or df for free space calculation'),
 40 40 cfg.BoolOpt('nfs_sparsed_volumes',
 41 41 default=True,
 42 42 help=('Create volumes as sparsed files which take no space.'
 43 43 'If set to False volume is created as regular file.'
 44 - 'In such case volume creation takes a lot of time.'))]
  44 + 'In such case volume creation takes a lot of time.')),
  45 + cfg.StrOpt('nfs_mount_options',
  46 + default=None,
  47 + help='Mount options passed to the nfs client. See section '
  48 + 'of the nfs man page for details'),
  49 +]

    NFS block storage driver documentation

    This commit includes some initial basic documentation on the NFS block
    storage driver. The Ops guide was also updated to briefly explain the
    difference between the NFS driver and other traditional block storage
    drivers.
