Bug Description

IBM Spectrum Scale cinder driver (GPFS) fails to initialize the driver while doing the _same_filesystem check locally. Ideally, it should do the check on the Spectrum Scale node where the actual GPFS file system is mounted. This issue will only occur when gpfs_images_share_mode is set to copy_on_write.

Fixed copy-on-write mode in GPFS NFS driver

    IBM Spectrum Scale cinder driver (GPFS) support copy-on-write feature
    in all the configuration. Resolving the bug mentioned below will
    enable mmclone feature of the IBM Spectrum Scale filesystem to provide
    better performance while configured in GPFS NFS mode.
