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.<br class="">

<div text="#000000" bgcolor="#FFFFFF" class=""> Hi,<br class="">
<br class="">
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 class="">
<br class="">
1. Created a gluster storage domain which is
backed by gluster volume with replica 3. <br class="">
2. Killed one brick process. So only two
bricks are running in replica 3 setup.<br class="">
3. Created two VMs<br class="">
4. Started some IO using fio on both of the
VMs<br class="">
5. After some time got the following error in
gluster mount and VMs moved to paused state.<br class="">
