The engine log looping with "Volume contains apparently corrupt bricks"- 
is when engine tries to get information from gluster CLI about the 
volumes and updates its database. These errors do not affect the 
functioning of the storage domain and running virtual machines, but 
affect the monitoring/management of the gluster volume from oVirt.

Now to identify the cause of the error - the logs indicate that the 
gluster's server uuid has either not been updated/ or is different in 
the engine. Could be one of these scenarios
1. Did you create the cluster with only virt service enabled and later 
enable gluster service? In this case, the gluster server uuid may not be 
updated. You will need to put host to maintenance and then activate it 
to resolve this

2. Did you re-install the gluster server nodes after adding it to oVirt? 
If this is the case, we need to investigate further how there's a mismatch.
