[ovirt-users] vm pauses with "vm has paused due to unknown storage error

[Krutika Dhananjay]

Hi Bill,

After glusterfs 3.7.11, around 4-5 bugs were found in sharding and
replicate modules and fixed, some of them causing the VM(s) to pause. Could
you share the glusterfs client logs from around the time the issue was
seen? This will help me confirm it's the same issue, or even debug further
if this is a new issue.
