File Level Restore for BTRFS and SDP for VE 8.1
------------------------------------------------

- Use normal approach for File level restore
- When "mount Task" is ok, SSH to Linux proxy
- Unmount the /tsmmount/ disks

  # > umount /tsmmount/mount_export/ltest01-t/2017-03-16-22_14_19/Volume1
  # > umount /tsmmount/mount_export/ltest01-t/2017-03-16-22_14_19/Volume2

- scan for BTRFS filesystems

  # > btrfs filesystem show

  Label: none  uuid: xxxxxxxxx-xxxx-xxxx-xxxx-xxxac225xxxx
        Total devices 1 FS bytes used 7.66GiB
        devid    1 size 13.99GiB used 9.57GiB path /dev/sdb2

- now we know /dev/sdb2 is BTRFS

- Mount the filesystem

  # > mkdir /tsmmount-btrfs 
  # > mount /dev/sdb2 /tsmmount-btrfs

- Scan for BTRFS subvolumes

  # > btrfs subvolume list -a /tsmmount-btrfs

  ID 262 gen 28909 top level 257 path <FS_TREE>/@/home
  ID 263 gen 30579 top level 257 path <FS_TREE>/@/opt
  ID 264 gen 8033 top level 257 path <FS_TREE>/@/srv
  ID 265 gen 31000 top level 257 path <FS_TREE>/@/tmp
  ID 266 gen 30579 top level 257 path <FS_TREE>/@/usr/local

- Mount HOME subvolume by using SUBVOLID

  # > mkdir /tsmmount-btrfs-subvol-home/
  # > mount -o subvolid=262 /dev/sdb2 /tsmmount-btrfs-subvol-home/

- Find the files, do the restore

- Cleanup

  # > cd
  # > umount /tsmmount*

- Return back to the GUI and run the "dismount" to remove iSCSI targets
  and liberate snapshot
