Hi all,
You asked: Any errors in ovirt-engine.log file ?
Yes, In the engine.log this error is repeated about every 3 minutes:

I am not sure why this says "Request timed out".
1) gluster volume list -> Still shows the deleted volume (test1)
2) gluster peer status -> Shows one of the peers twice with different

How did this happen? Are the hostname same for two hosts ?
I tried a gluster volume stop test1, with this result: volume stop:
test1: failed: Another transaction is in progress for test1. Please
try again after sometime.
can you restart glusterd and try to stop and delete the volume?
The etc-glusterfs-glusterd.vol.log shows no activity triggered by
trying to remove the test1 volume from the UI.
The ovirt-engine.log shows this repeating many times, when trying to
remove the test1 volume from the UI:
2017-04-12 07:57:38,049-07 INFO

can you restart ovirt-engine service because i see that "failed to
acquire lock". Once ovirt-engine is restarted some one who is holding
the lock should be release and things should work fine.
Last but not least, if none of the above works:
Login to all your nodes in the cluster.
rm -rf /var/lib/glusterd/vols/*
rm -rf /var/lib/glusterd/peers/*
systemctl restart glusterd on all the nodes.
Login to UI and see if any volumes / hosts are present. If yes, remove them.
This should clear things for you and you can start from basic.
Thanks much,
Andrew

Yet, It still shows in the web UI?
Any errors in ovirt-engine.log file ? if the volume is deleted from db
ideally it should be deleted from UI too. Can you go to gluster nodes
and check for the following:
1) gluster volume list -> should not return anything since you have
deleted the volumes.
2) gluster peer status -> on all the nodes should show that all the
peers are in connected state.
can you tail -f /var/log/ovirt-engine/ovirt-engine.log and gluster log
and capture the error messages when you try deleting the volume from UI?
Log what you have pasted in the previous mail only gives info and i
could not get any details from that on why volume delete is failing

The plot thickens…
I put all hosts in the cluster into maintenance mode, with the Stop
Gluster service checkbox checked. I then deleted the
/var/lib/glusterd/vols/test1 directory on all hosts. I then took the
host that the test1 volume was on out of maintenance mode. Then I
tried to remove the test1 volume from within the web UI. With no
luck, I got the message: Could not delete Gluster Volume test1 on
cluster 8000-1.
I went back and checked all host for the test1 directory, it is not
on any host. Yet I still can’t remove it…
Any suggestions?

Here is an update…
I checked the /var/log/glusterfs/etc-glusterfs-glusterd.vol.log on
the node that had the trouble volume (test1). I didn’t see any
errors. So, I ran a tail -f on the log as I tried to remove the
volume using the web UI. here is what was appended:
[2017-04-11 19:48:40.756360] I [MSGID: 106487]
[glusterd-handler.c:1474:__glusterd_handle_cli_list_friends]

[glusterd-handler.c:1537:__glusterd_handle_cli_get_volume]
0-management: Received get vol req
The message "I [MSGID: 106487]
[glusterd-handler.c:1474:__glusterd_handle_cli_list_friends]
0-glusterd: Received cli list req" repeated 6 times between
[2017-04-11 19:48:40.756360] and [2017-04-11 19:49:32.596536]
The message "I [MSGID: 106488]
[glusterd-handler.c:1537:__glusterd_handle_cli_get_volume]
0-management: Received get vol req" repeated 20 times between
[2017-04-11 19:48:42.238840] and [2017-04-11 19:49:34.082179]

[glusterd-handler.c:1474:__glusterd_handle_cli_list_friends]
0-glusterd: Received cli list req
I’m seeing that the timestamps on these log entries do not match the
time on the node.
The next steps
I stopped the glusterd service on the node with volume test1
I deleted it with: rm -rf /var/lib/glusterd/vols/test1
I started the glusterd service.
After starting the gluster service back up, the directory
/var/lib/glusterd/vols/test1 reappears.
I’m guessing syncing with the other nodes?
Is this because I have the Volume Option: auth allow *
Do I need to remove the directory /var/lib/glusterd/vols/test1 on all
nodes in the cluster individually?
thanks

Hi all,
The node is oVirt Node 4.1.1 with glusterfs-3.8.10-1.el7.
On the node I can not find /var/log/glusterfs/glusterd.log However,
there is a /var/log/glusterfs/glustershd.log
can you check if /var/log/glusterfs/etc-glusterfs-glusterd.vol.log
exists? if yes, can you check if there is any error present in that
file ?
What happens if I follow the four steps outlined here to remove the
volume from the node _BUT_, I do have another volume present in the
cluster. It too is a test volume. Neither one has any data on them.
So, data loss is not an issue.
Running those four steps will remove the volume from your cluster .
If the volumes what you have are test volumes you could just follow
the steps outlined to delete them (since you are not able to delete
from UI) and bring back the cluster into a normal state.

Hi Ovirt users,
I’m a newbie to oVirt and I’m having trouble deleting a test
gluster volume. The nodes are 4.1.1 and the engine is 4.1.0
When I try to remove the test volume, I click Remove, the
dialog box prompting to confirm the deletion pops up and after
I click OK, the dialog box changes to show a little spinning
wheel and then it disappears. In the end the volume is still there.
with the latest version of glusterfs & ovirt we do not see any issue
with deleting a volume. Can you please check
/var/log/glusterfs/glusterd.log file if there is any error present?
The test volume was distributed with two host members. One of
the hosts I was able to remove from the volume by removing the
host form the cluster. When I try to remove the remaining host
in the volume, even with the “Force Remove” box ticked, I get
this response: Cannot remove Host. Server having Gluster volume.
What to try next?
since you have already removed the volume from one host in the
cluster and you still see it on another host you can do the
following to remove the volume from another host.
1) Login to the host where the volume is present.
2) cd to /var/lib/glusterd/vols
3) rm -rf <vol_name>
4) Restart glusterd on that host.
And before doing the above make sure that you do not have any other
volume present in the cluster.
Above steps should not be run on a production system as you might
loose the volume and data.
Now removing the host from UI should succed.
P.S. I’ve tried to join this user group several times in the
past, with no response.
Is it possible for me to join this group?
Regards,
Andrew
