The volume set fails, but the op-version actually got bumped up.
There are no problems functionally

    glusterd: fix op-version bump up flow
    
    If a cluster is upgraded from 3.5 to latest version, gluster volume set all
    cluster.op-version <VERSION> will throw an error message back to the user saying
    unlocking failed. This is because of trying to release a volume wise lock in
    unlock phase as the lock was taken cluster wide. The problem surfaced because
    the op-version is updated in commit phase and unlocking works in the v3
    framework where it should have used cluster unlock.
    
    Fix is to decide which lock/unlock is to be followed before invoking lock phase

Comment 3 Nagaprasad Sathyanarayana 2015-10-25 14:43:27 UTC

Fix for this BZ is already present in a GlusterFS release. You can find clone of this BZ, fixed in a GlusterFS release and closed. Hence closing this mainline BZ as well.

Comment 4 Niels de Vos 2016-06-16 13:27:16 UTC

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.8.0, please open a new bug report.

glusterfs-3.8.0 has been announced on the Gluster mailinglists [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
