Hi Simone,
a short mail chain in gluster-users Amar confirmed my suspicion that
Gluster v5.5 is performing a little bit slower than 3.12.15 .
In result the sanlock reservations take too much time.
Thanks for the report!
I have updated my setup and uncached (used lvm caching in writeback
mode)
my data bricks and used the SSD for the engine volume.Now the engine is
running quite well and no more issues were observed.
This definitively helps, but for my experience the network speed is really
determinant here.
Can you describe your network configuration?
A 10 Gbps net is definitively fine here.
A few bonded 1 Gbps nics could work.
A single 1 Gbps nic could be an issue.
Can you share any thoughts about oVirt being updated to Gluster v6.x
? I
know that there are any hooks between vdsm and gluster and I'm not sure how
vdsm will react on the new version.
It's definitively planned, see: https://bugzilla.redhat.com/1693998
<https://bugzilla.redhat.com/show_bug.cgi?id=1693998>
I'm not really sure about its time plan.

Strahil Nikolov
