Well guys, I can say now that I have a real problem, maybe between ovirt and gluster storage, but I can't be sure. Yesterday, I wanted to clone a VM (named "crij2") from a snapshot, but (this is another problem I think) the UI never gave me the popup (blank window with the cursor with a message 400 after a timeout). So I decided to export it, then import it. The export/import finally works, but when it was working, some VMs became randomly unresponsives, and one restarted on error. At this time, the engine was on "ginger" node.

Exit message: User shut down from within the guest 27 oct. 2018 18:39:25 User admin@internal-authz got disconnected from VM crij2. I checked the network and gluster since it works but saw absolutly nothing special. The storage network was not too sollicited (bwm-ng indicated max 50MB/s on bond1). Gluster log no errors too (even if the engine reported some timeouts).
This morning I started to search why and wanted to submit to you some logs on this thread, but I found something that had not caught my attention before, so I ask about it before all.
I recall the configuration : 3 hosts with gluster (replica 2 + arbiter). The volumes are on a separate network (bond1 is an aggregation of 2 Gb cards while ovirmgmt is on bond0, 2 NICs in backup mode). For now, I have only declared the first 2 nodes in the engine GUI as ovirt nodes, because the arbiter is a small machine with a smaller CPU (and only 8Gb memory), that needed to downgrade the cluster from Sandybridge to Nehalem. Maybe it was an error. The storagenetwork on bond1 was declared too in the GYUI, but not yet as a gluster storage.
The Gluster volumes themselves were declared on the storage network by using names indicated in /etc/hosts on bond1 network. Here is a volume status : # gluster volume status Status of volume: DATA01 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick victorstorage.local.systea.fr:/home/d ata01/data01/brick 49152 0 Y 2489 Brick gingerstorage.local.systea.fr:/home/d ata01/data01/brick 49152 0 Y 2531 Brick eskarinastorage.local.systea.fr:/home /data01/data01/brick 49153 0 Y 28119 Self-heal Daemon on localhost N/A N/A Y 24859 Self-heal Daemon on eskarinastorage.local.s ystea.fr N/A N/A Y 30725 Self-heal Daemon on victorstorage.local.sys tea.fr N/A N/A Y 2810

Task Status of Volume ISO ------------------------------- But, a df on the nodes shows that all volumes except ENGINE was mounted on ovirmgmt network (hosts names without "storage") :

I can't remember how it was declared at install time, maybe I had not seen that, but if I tried to had a domain now, gluster managed, effectively it proposes to me only the nodes by their ovirmgmt names, not storage names.
Names are only known in the /etc/hosts of all nodes + engine, there is no DNS for this local addresses.
So : in your opinion, can this configuration be a (the) source of my problems ? And have you an idea how I could correct this now, without loosing anything ?
I don't think this is the cause of your issues. Are there errors in vdsm logs? Do you have issues with storage latency (can you check the gluster volume profile output?)
Thanks for all suggestions.
