[ovirt-users] [Gluster-users] op-version for reset-brick (Was: Re: Upgrading HC from 4.0 to 4.1)

[Atin Mukherjee]

OK, so the log just hints to the following:

[2017-07-05 15:04:07.178204] E [MSGID: 106123]
[glusterd-mgmt.c:1532:glusterd_mgmt_v3_commit] 0-management: Commit failed
for operation Reset Brick on local node
[2017-07-05 15:04:07.178214] E [MSGID: 106123]
[glusterd-replace-brick.c:649:glusterd_mgmt_v3_initiate_replace_brick_cmd_phases]
0-management: Commit Op Failed

While going through the code, glusterd_op_reset_brick () failed resulting
into these logs. Now I don't see any error logs generated from
glusterd_op_reset_brick () which makes me thing that have we failed from a
place where we log the failure in debug mode. Would you be able to restart
glusterd service with debug log mode and reran this test and share the log?
