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. Copy of the event log :

27 oct. 2018 20:32:12 VM crij2 started on Host victor.local.systea.fr
27 oct. 2018 20:31:37 VM crij2 was started by admin@internal-authz (Host: victor.local.systea.fr).

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 :

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

victor.local.systea.fr:/DATA02          5,0T    226G  4,7T   5% /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02
victor.local.systea.fr:/ISO             1,3T    425G  862G  33% /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_ISO
victor.local.systea.fr:/EXPORT          1,3T    425G  862G  33% /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_EXPORT

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 ?

Thanks for all suggestions.

Hi,
I forgot to look in the /var/log/messages file on the host ! What a shame :/
Here is the messages file at the time of the error : https://gist.github.com/fsoyer/4d1247d4c3007a8727459efd23d89737
At the sasme time, the second host as no particular messages in its log.
Does anyone have an idea of the source problem ?
 
The problem started when sanlock could not renew storage leases held by some processes:
 
Oct 16 11:01:46 victor sanlock[904]: 2018-10-16 11:01:46 2945585 [4167]: s3 delta_renew read timeout 10 sec offset 0 /rhev/data-center/mnt/glusterSD/victor.local.systea.fr:_DATA02/ffc53fd8-c5d1-4070-ae51-2e91835cd937/dom_md/ids

After 80 seconds, the vms are terminated by sanlock:
 
Oct 16 11:02:19 victor sanlock[904]: 2018-10-16 11:02:18 2945617 [904]: s1 check_our_lease failed 80

But process 13823 cannot be killed, since it is blocked on storage, so sanlock send many more
TERM signals:
 
Oct 16 11:02:33 victor sanlock[904]: 2018-10-16 11:02:33 2945633 [904]: s1 kill 13823 sig 15 count 17
 
The VM finally dies after 17 retries:
 
Oct 16 11:02:33 victor sanlock[904]: 2018-10-16 11:02:33 2945633 [904]: dead 13823 ci 10 count 17
 
We can see the same flow for other processes (HA VMs?)
 
This allows the system to start the HA VM
on another host, which is what we see in the events log in the first message.
 
Trying to restart VM npi2 on Host victor.local.systea.fr
16 oct. 2018 11:02:33
Highly Available VM npi2 failed. It will be restarted automatically.
16 oct. 2018 11:02:33
VM npi2 is down with error. Exit message: VM has been terminated on the host.
 
If the VMs were not started successfully on the other hosts, maybe the storage domain
used for VM lease is not accessible?
 
It is recommended to choose the same storage domain used by the other VM disks for
the VM lease.
 
Also check that all storage domains are accessible - if they are not you will have warnings
in /var/log/vdsm/vdsm.log.

with engine. log : https://gist.github.com/fsoyer/e3b74b4693006736b4f737b642aed0ef
searching for "Failed to acquire lock" I see a post about sanlock.log. Here it is at the time of the restart : https://gist.github.com/fsoyer/8d6952e85623a12f09317652aa4babd7
(hope that you can display this gists)

First question : there is all the days those message "delta_renew long write time".  What does this mean ? Even if I suspect some storage problem, I don't see latency on it (configuration described bellow).
Second question : what append that force some VMs (not all, and not and the sams host !) to restart ? Where and what must I search for ?
Thanks

Configuration
2 DELL R620 as ovirt hosts (4.2.8-2) with hosted-engine, also members of a gluster 3.12.13-1 cluster with an arbiter (1 DELL R310, non-ovirt). The DATAs and ENGINE storages are on gluster volumes. Around 11am, I do not see any specific messages in glusterd.log or glfsheal-*.log. Gluster is on a separate network (2*1G bond mode 4=aggegation) than ovirmgmt (2*1G bond mode 1=failover).
