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:

This is probably some refresh bug in the UI, Sahina might be able to tell you.

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

But it does  say something. All these gfids of completed heals in the log below are the for the ones that you have given the getfattr output of. So what is likely happening is there is an intermittent connection problem between your mount and the brick process, leading to pending heals again after the heal gets completed, which is why the numbers are varying each time. You would need to check why that is the case.
Hope this helps,
Ravi

Hi,

following your suggestion, I've checked the "peer" status and I found that there is too many name for the hosts, I don't know if this can be the problem or part of it:

gluster peer status on NODE01:

Number of Peers: 2

Hostname: dnode02.localdomain.local

Uuid: 7c0ebfa3-5676-4d3f-9bfa-7fff6afea0dd

All these ip are pingable and hosts resolvible across all 3 nodes but, only the 10.10.10.0 network is the decidated network for gluster  (rosolved using gdnode* host names) ... You think that remove other entries can fix the problem? So, sorry, but, how can I remove other entries? 

I don't think having extra entries could be a problem. Did you check the fuse mount logs for disconnect messages that I referred to in the other email?

And, what about the selinux?

Not sure about this. See if there are disconnect messages in the mount logs first.

Thank you
