Ok was just seeing if matched up to the issues latest 3.7.x releases have with zfs and sharding but doesn't look like your issue.

 In your logs I see it mounts with thee commands.  What happens if you use same to a test dir?

 /usr/bin/mount -t glusterfs -o backup-volfile-servers=172.16.0.12:172.16.0.13 172.16.0.11:/ovirt /rhev/data-center/mnt/glusterSD/172.16.0.11:_ovirt

It then umounts it and complains short while later of permissions.

StorageServerAccessPermissionError: Permission settings on the specified path do not allow access to the storage. Verify permission settings on the specified storage path.: 'path = /rhev/data-center/mnt/glusterSD/172.16.0.11:_ovirt'

Are the permissions of dirs to /rhev/data-center/mnt/glusterSD/172.16.0.11:_ovirt as expected?

How about on the bricks anything out of place?

Is gluster still using same options as before?  could it have reset the user and group to not be 36?

Hi,

Issue: Cannot find master domain

Changes applied before issue started to happen: replaced 172.16.0.12:/data/brick1/brick1 with 172.16.0.12:/data/brick3/brick3, did minor package upgrades for vdsm and glusterfs

vdsm log: https://paste.fedoraproject.org/396842/

Any errrors in glusters brick or server logs?  The client gluster logs from ovirt?

Brick errors:

(Both repeated many times)

Server errors:

None

Client errors:

None

 

yum log: https://paste.fedoraproject.org/396854/

What version of gluster was running prior to update to 3.7.13? 

3.7.11-1 from gluster.org repository(after update ovirt switched to centos repository)

What file system do your bricks reside on and do you have sharding enabled? 

Did it create gluster mounts on server when attempting to start?

As I checked the master domain is not mounted on any nodes.

Restarting vdsmd generated following errors:
