I just noticed this in the Alerts tab: Detected deletion of volume test1 on cluster 8000-1, and deleted it from engine DB.
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

I went back and checked all host for the test1 directory, it is not on any host. Yet I still cant remove it
Any suggestions?

I checked the /var/log/glusterfs/etc-glusterfs-glusterd.vol.log on the node that had the trouble volume (test1). I didnt 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:

Im 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. Im 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

Hi Ovirt users, Im a newbie to oVirt and Im 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. Ive tried to join this user group several times in the past, with no response. Is it possible for me to join this group?
