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:<br>
<br>
1) gluster volume list -> should not return anything since you
have deleted the volumes.<br>
<br>
2) gluster peer status -> on all the nodes should show that all
the peers are in connected state.<br>
<br>
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?<br>
<br>
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<br>

<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>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>

can you check if

yes, can you check if there is any error present in that

<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>

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>

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?

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>
