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

I am not able to resume a VM

gluster client quorum issue. Here
is what happened in my setup. <br

<br class="">
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

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
