I did that. But still I am facing the same issue. VM get paused when I
do some I/O using fio on some disks backed by gluster. I am not able to
resume the VM after this. Now only way is to bring down the VM and run
again. It runs successfully on the same host without any issue.

One brick process is purposefully killed but remaining two bricks
are up and running.

Hi,<br>
<br>
I am not able to resume a VM which was
paused because of gluster client quorum issue.
Here is what happened in my setup. <br>
<br>
1. Created a gluster storage domain which is
backed by gluster volume with replica 3. <br>
2. Killed one brick process. So only two
bricks are running in replica 3 setup.<br>
3. Created two VMs<br>
4. Started some IO using fio on both of the
VMs<br>
5. After some time got the following error in
gluster mount and VMs moved to paused state.<br>
