[ovirt-users] ovirt 4.1 hosted engine hyper converged on glusterfs 3.8.10 : "engine" storage domain alway complain about "unsynced" elements

Fri Jul 21 18:11:10 UTC 2017

Hi,

Sorry for follow up again, but, checking the ovirt interface I've found
that ovirt report the "engine" volume as an "arbiter" configuration and the
"data" volume as full replicated volume. Check these screenshots:

But the "gluster volume info" command report that all 2 volume are full
replicated:
