glusterfs.git/tests/bugs/glusterd/bug-1322145-disallow-detatch-peer.t, branch v4.0dev1 glusterd : Disallow peer detach if snapshot bricks exist on it 2017-04-01T01:53:10+00:00 Gaurav Yadav gyadav@redhat.com 2017-03-16T09:26:39+00:00 1c92f83ec041176ad7c42ef83525cda7d3eda3c5 Problem : - Deploy gluster on 2 nodes, one brick each, one volume replicated - Create a snapshot - Lose one server - Add a replacement peer and new brick with a new IP address - replace-brick the missing brick onto the new server (wait for replication to finish) - peer detach the old server - after doing above steps, glusterd fails to restart. Solution: With the fix detach peer will populate an error : "N2 is part of existing snapshots. Remove those snapshots before proceeding". While doing so we force user to stay with that peer or to delete all snapshots.

Problem :
- Deploy gluster on 2 nodes, one brick each, one volume replicated
- Create a snapshot
- Lose one server
- Add a replacement peer and new brick with a new IP address
- replace-brick the missing brick onto the new server
  (wait for replication to finish)
- peer detach the old server
- after doing above steps, glusterd fails to restart.

Solution:
  With the fix detach peer will populate an error : "N2 is part of
  existing snapshots. Remove those snapshots before proceeding".
  While doing so we force user to stay with that peer or to delete
  all snapshots.
