This sounds like
https://bugzilla.redhat.com/1271771

This patch may fix this: https://gerrit.ovirt.org/#/c/27334/
Would you like to test it?

To dig deeper, we need the logs:
- /var/log/vdsm/vdsm.log (the one showing this timeframe)
- /var/log/sanlock.log
- /var/log/messages
- /var/log/glusterfs/<server>:<remotepath>-<date>.log
