Bug ID: 1540660
Summary: Introduce lock recovery options to prevent possible
post-upgrade mount failures
Product: GlusterFS
Version: 4.0
Component: protocol
Keywords: Triaged
Assignee: bugs at gluster.org
Reporter: srangana at redhat.com
CC: amukherj at redhat.com, anoopcs at redhat.com,
bugs at gluster.org
Depends On: 1540659
Patch being referred to in 4.0 would be: https://review.gluster.org/#/c/19392/
+++ This bug was initially created as a clone of Bug #1540659 +++
This patch: https://review.gluster.org/12363 removes the following options,
features.lock-heal
features.grace-timeout
Current worry is that if a volume has these options enabled, we would
post-upgrading the server fail for client mounts (or even in other places).
Also, removing these options post-upgrade may fail, as the options are not
available, and hence may need editing the vol files.
We need to test and ensure that the above occurs, and if it does, we need to
fix the situation in consultation with the glusterd team.
Current thoughts for fixing this up is to add these options back but as No-Ops,
such that post upgrade functionality is removed, but the presence of the option
itself does not cause failures.
