Hi all,

We have an ovirt cluster hyperconverged with hosted engine on 3 full replicated node . This cluster have 2 gluster volume:

- data: volume for the Data (Master) Domain (For vm)
- engine: volume fro the hosted_storage  Domain (for hosted engine)

We have this problem: "engine" gluster volume have always unsynced elements and we cant' fix the problem, on command line we have tried to use the "heal" command but elements remain always unsynced .... 

Below the heal command "status":

running the "gluster volume heal engine" don't solve the problem...

Some extra info:

We have recently changed the gluster from: 2 (full repliacated) + 1 arbiter to 3 full replicated cluster but i don't know this is the problem...

The "data" volume is good and healty and have no unsynced entry.

Ovirt refuse to put the node02 and node01 in "maintenance mode" and complains about "unsynced elements"

How can I fix this?
Thank you
