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?

I put all hosts in the cluster into maintenance mode, with the Stop Gluster=

directory on all hosts. I then took the host that the test1 volume was on o=

the web UI. With no luck, I got the message: Could not delete Gluster Volu=

I went back and checked all host for the test1 directory, it is not on any =
host. Yet I still can=92t remove it=85
Any suggestions?

Here is an update=85
I checked the /var/log/glusterfs/etc-glusterfs-glusterd.vol.log on the node=
that had the trouble volume (test1). I didn=92t 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:__g=

I=92m 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=92m 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

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 outl=
ined to delete them (since you are not able to delete from UI) and bring ba=
ck the cluster into a normal state.

Hi Ovirt users,
I=92m a newbie to oVirt and I=92m having trouble deleting a test gluster vo=
lume. 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 prompt=
ing to confirm the deletion pops up and after I click OK, the dialog box ch=
anges to show a little spinning wheel and then it disappears. In the end th=
e volume is still there.
with the latest version of glusterfs & ovirt we do not see any issue with d=
eleting 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 w=
as able to remove from the volume by removing the host form the cluster. Wh=
en I try to remove the remaining host in the volume, even with the =93Force=
Remove=94 box ticked, I get this response: Cannot remove Host. Server havi=
ng 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 vol=
ume 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=92ve tried to join this user group several times in the past, with n=
o response.
Is it possible for me to join this group?
Regards,
Andrew
