You need to set the gluster.server-quorum-ratio to 51%


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.

Ramesh

    *cluster.server-quorum-type*:server
    *cluster.quorum-type*:auto
    *gluster.server-quorum-ratio is not set.*

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

        Hi,

           I am not able to resume a VM which was paused because of
        gluster client quorum issue. Here is what happened in my setup.

        1. Created a gluster storage domain which is backed by
        gluster volume with replica 3.
        2. Killed one brick process. So only two bricks are running
        in replica 3 setup.
        3. Created two VMs
        4. Started some IO using fio on both of the VMs
        5. After some time got the following error in gluster mount
        and VMs moved to paused state.
                 " server 10.70.45.17:49217
        <http://10.70.45.17:49217> has not responded in the last 42
        seconds, disconnecting."
              "vmstore-replicate-0:
        e16d1e40-2b6e-4f19-977d-e099f465dfc6: Failing WRITE as quorum
        is not met"
              more gluster mount logs at http://pastebin.com/UmiUQq0F
        6. After some time gluster quorum is active and I am able to
        write the the gluster file system.
        7. When I try to resume the VM it doesn't work and I got
        following error in vdsm log.
