[ovirt-users] glusterfs heal issues [Solved]

[Gary Pedretty]

I figured it out.  I forgot that these gluster volumes as recommended by the Ovirt Glusterized setup were created as  Replica 3 Arbiter 1 volumes, so now I understand what that truly means,  One brick only contains the directory and meta data and so will always be smaller actual disk use.   Sorry for the confusion..

The self heal seemed to startup and the Ovirt Management portal showed healing taking place in the Volumes/Brick tab.  Later it showed everything ok.  This is a replica 3 volume.  I noticed however that the brick tab was not showing even use of the 3 bricks and looking on the actual hosts a df command also shows uneven use of the bricks.  However gluster volume heal (vol) info shows zero entries for all bricks.  There are no errors reported in the Data Center or Cluster, yet I see this uneven use of the bricks across the 3 hosts.
