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.
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?
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

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,

Is it possible for me to join this group?

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 i=
s a /var/log/glusterfs/glustershd.log
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.

What happens if I follow the four steps outlined here to remove 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.

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.

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>

a tail -f on the log as I tried to remove the volume using the web UI. here=

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

The plot thickens=85
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 o=
ut 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 Volu=
me 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=92t remove it=85
Any suggestions?

I checked the /var/log/glusterfs/etc-glusterfs-glusterd.vol.log on the node=

a tail -f on the log as I tried to remove the volume using the web UI. here=

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=

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?

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:

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?

Andrew

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 cant 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 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:
[2017-04-11 19:48:40.756360] I [MSGID: 106487]

The message "I [MSGID: 106487]

[2017-04-11 19:48:40.756360] and [2017-04-11 19:49:32.596536]
The message "I [MSGID: 106488]

[glusterd-handler.c:1474:__glusterd_handle_cli_list_friends]
0-glusterd: Received cli list req
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

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 ?

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.

Running those four steps will remove the volume from your

since you have already removed the volume from one host

can do the following to remove the volume from another

Hi all,
You asked: Any errors in ovirt-engine.log file ?
Yes, In the engine.log this error is repeated about every 3 minutes:

can you tail -f /var/log/ovirt-engine/ovirt-engine.log and gluster log and =

The plot thickens=85
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 o=
ut 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 Volu=
me 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=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=

The message "I [MSGID: 106487] [glusterd-handler.c:1474:__glusterd_handle_c=
li_list_friends] 0-glusterd: Received cli list req" repeated 6 times betwee=

The message "I [MSGID: 106488] [glusterd-handler.c:1537:__glusterd_handle_c=

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

Hi all,
The node is oVirt Node 4.1.1 with glusterfs-3.8.10-1.el7.

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 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?

I am not sure why this says "Request timed out".
1) gluster volume list -> Still shows the deleted volume (test1)
2) gluster peer status -> Shows one of the peers twice with different
uuids:
Hostname: 192.168.10.109Uuid:

How did this happen? Are the hostname same for two hosts ?
I tried a gluster volume stop test1, with this result: volume stop:
test1: failed: Another transaction is in progress for test1. Please
try again after sometime.
can you restart glusterd and try to stop and delete the volume?
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:
2017-04-12 07:57:38,049-07 INFO

can you restart ovirt-engine service because i see that "failed to
acquire lock". Once ovirt-engine is restarted some one who is holding
the lock should be release and things should work fine.
Last but not least, if none of the above works:
Login to all your nodes in the cluster.
rm -rf /var/lib/glusterd/vols/*
rm -rf /var/lib/glusterd/peers/*
systemctl restart glusterd on all the nodes.
Login to UI and see if any volumes / hosts are present. If yes, remove them.
This should clear things for you and you can start from basic.
Thanks much,
Andrew

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

can you restart ovirt-engine service because i see that "failed to
acquire lock". Once ovirt-engine is restarted some one who is
holding the lock should be release and things should work fine.<br>
<br>
Last but not least, if none of the above works:<br>
<br>
Login to all your nodes in the cluster.<br>
rm -rf /var/lib/glusterd/vols/*<br>
rm -rf /var/lib/glusterd/peers/*<br>
systemctl restart glusterd on all the nodes.<br>
<br>
Login to UI and see if any volumes / hosts are present. If yes,
remove them.<br>
<br>
This should clear things for you and you can start from basic.<br>

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>

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

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>

Hi all,
In the end, I ran this on each host node and is what worked:
systemctl stop glusterd && rm -rf /var/lib/glusterd/vols/* && rm -rf
/var/l=
ib/glusterd/peers/*
Thanks so much for your help.
P.S. I work as a sys admin for the San Jose library. Part of my job satisfa=
ction comes from knowing that the work I do here goes directly back into th=
is community. We=92r fortunate that you, your coworkers, and Red Hat do so =
much to give back. I have to imagine you too feel this sense of satisfactio=
n. Thanks again=85
P.S.S. I never did hear back from users(a)ovirt.org mailing list. I did fill =
out the fields on this page: https://lists.ovirt.org/mailman/listinfo/users=
. Yet, everytime I send them an email I get: Your message to Users awaits m=
oderator approval. Is there a secret handshake, I=92m not aware of?
Regards,
Andrew

Yes, In the engine.log this error is repeated about every 3 minutes:

I am not sure why this says "Request timed out".

How did this happen? Are the hostname same for two hosts ?
I tried a gluster volume stop test1, with this result: volume stop: test1: =

r sometime.
can you restart glusterd and try to stop and delete the volume?
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:
2017-04-12 07:57:38,049-07 INFO [org.ovirt.engine.core.bll.lock.InMemoryLo=

can you restart ovirt-engine service because i see that "failed to acquire =
lock". Once ovirt-engine is restarted some one who is holding the lock sho=
uld be release and things should work fine.
Last but not least, if none of the above works:
Login to all your nodes in the cluster.
rm -rf /var/lib/glusterd/vols/*
rm -rf /var/lib/glusterd/peers/*
systemctl restart glusterd on all the nodes.
Login to UI and see if any volumes / hosts are present. If yes, remove them=
.
This should clear things for you and you can start from basic.
Thanks much,
Andrew

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

Hi all,
In the end, I ran this on each host node and is what worked:

Thanks so much for your help.
YW :-)
P.S. I work as a sys admin for the San Jose library. Part of my job
satisfaction comes from knowing that the work I do here goes directly
back into this community. Wer fortunate that you, your coworkers, and
Red Hat do so much to give back. I have to imagine you too feel this
sense of satisfaction. Thanks again
P.S.S. I never did hear back from users(a)ovirt.org mailing list. I did
fill out the fields on this page:
https://lists.ovirt.org/mailman/listinfo/users. Yet, everytime I send
them an email I get: Your message to Users awaits moderator approval.
Is there a secret handshake, Im not aware of?
Ideally you should be able to. Not
sure why . May be a separate email
thread to this user list should help you get the right answer ?
Regards,
Andrew

can you restart ovirt-engine service because i see that "failed to
acquire lock". Once ovirt-engine is restarted some one who is holding
the lock should be release and things should work fine.
Last but not least, if none of the above works:
Login to all your nodes in the cluster.
rm -rf /var/lib/glusterd/vols/*
rm -rf /var/lib/glusterd/peers/*
systemctl restart glusterd on all the nodes.
Login to UI and see if any volumes / hosts are present. If yes, remove
them.
This should clear things for you and you can start from basic.

can you restart ovirt-engine service because i see that "failed
to acquire lock". Once ovirt-engine is restarted some one who
is holding the lock should be release and things should work
fine.<br>
<br>
Last but not least, if none of the above works:<br>
<br>
Login to all your nodes in the cluster.<br>
rm -rf /var/lib/glusterd/vols/*<br>
rm -rf /var/lib/glusterd/peers/*<br>
systemctl restart glusterd on all the nodes.<br>
<br>
Login to UI and see if any volumes / hosts are present. If yes,
remove them.<br>
<br>
This should clear things for you and you can start from basic.<br>

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>

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

with the latest version of glusterfs & ovirt

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>

Im seeing that the timestamps on these log entries do not match the
time on the node.
gluster logs are in UTC format. That is the reason you might be
seeing a
different timestamp on your node and in the gluster logs.
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?
yes, since you deleted it only one one
node.
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?
you need to remove the file
/var/lib/glusterd/vols/test1 on all nodes
and restart glusterd service on all the nodes in the cluster.

Running those four steps will remove the volume from your cluster . If

gluster logs are in UTC format. That is the reason you might be
seeing a different timestamp on your node and in the gluster logs.<br>

you need to remove the file /var/lib/glusterd/vols/test1 on all

can you check if

yes, can you check if there is any error present in that file ?<span

<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>
</blockquote>
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>When I try to remove the test volume, I
click Remove, the dialog box prompting to

end the volume is still there.</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

from the volume by removing the host form the
cluster. When I try to remove the remaining host

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>
