Hi all,
You asked: Any errors in ovirt-engine.log file ?
Yes, In the engine.log this error is repeated about every 3 minutes:
2017-04-12 07:16:12,554-07 ERROR

I tried a gluster volume stop test1, with this result: volume stop: test1:

sometime.
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:

Thanks much,

I just noticed this in the Alerts tab: Detected deletion of volume test1 on

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] 0-glusterd:
Received cli list req
[2017-04-11 19:48:42.238840] I [MSGID: 106488]
[glusterd-handler.c:1537:__glusterd_handle_cli_get_volume] 0-management:

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]
[2017-04-11 19:51:41.556077] I [MSGID: 106487]
[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
