RCA:

Brick is not coming up after reboot because of fsid comparison failing at the
time of start brick. The fsid comparison is failed because fsid is changed after
reboot the node.To resolve the same compare volume_id xattr with saved volume_uid before start/attach a brick.volume_id is populated on a brick_root path at the time of creating a volume and same volume_id is stored on the backend by glusterd.


Thanks

COMMIT: https://review.gluster.org/20638 committed in master by "Atin Mukherjee" <amukherj> with a commit message- glusterd: Compare volume_id before start/attach a brick

Problem: After reboot a node brick is not coming up because
         fsid comparison is failed before start a brick

Solution: Instead of comparing fsid compare volume_id to
          resolve the same because fsid is changed after
          reboot a node but volume_id persist as a xattr
          on brick_root path at the time of creating a volume.
