[Gluster-users] GlusterFS 3.6.1 breaks VM images on cluster node restart

[Andrus, Brian Contractor]

Roger
I was using the last latest 3.7.0 and before that 3.6.3
So far I have NOT had the issue with 3.7.1, so that makes me quite happy.

Hi Brian,

which version were you using before 3.7.1? Did that problem occur with version 3.7.1 meanwhile?

Greetings,
Roger Lehmann

Once that happens, heal doesn't work often and while it is in such a state, the VM often becomes unresponsive. I've had to pick on of the qcow files from a brick, copy it somewhere, delete the file from gluster and then copy the file from a brick to gluster.
