[ovirt-users] ovirt 3.6.6 and gluster 3.7.13

Thu Jul 21 16:47:33 UTC 2016

Hi David,

My backend storage is ZFS.

I thought about moving from FUSE to NFS mounts for my Gluster volumes to
help test.  But since I use hosted engine this would be a real pain.  Its
difficult to modify the storage domain type/path in the
hosted-engine.conf.  And I don't want to go through the process of
re-deploying hosted engine.
