<div>Here is an update…</div>
<div><br>
</div>
<div>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:</div>
<div><br>
</div>
<div>[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</div>
<div>[2017-04-11 19:48:42.238840] I [MSGID: 106488] [glusterd-handler.c:1537:__glusterd_handle_cli_get_volume] 0-management: Received get vol req</div>
<div>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]</div>
<div>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]</div>

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

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 ?<span style="color: rgb(84, 84, 84); font-family: arial,

<div>What happens if I follow the four steps outlined here to remove the volume from the node
<u>BUT</u>, 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.</div>
</div>

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.<br>

<div>Hi Ovirt users,</div>
<div>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</div>
<div><br>
</div>
<div>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.</div>
</div>

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.

<div>What to try next?</div>

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.<br>
<br>
1) Login to the host where the volume is present.<br>
2) cd to /var/lib/glusterd/vols<br>
3) rm -rf <vol_name><br>
4) Restart glusterd on that host.<br>
<br>
And before doing the above make sure that you do not have any other volume present in the cluster.<br>
<br>
Above steps should not be run on a production system as you might loose the volume and data.
<br>
<br>
Now removing the host from UI should succed.<br>
