Sorry, hit send by accident.
More details :
When I notice that the engine is down, if I type hosted-engine --vm-status
on any hosts, it hangs and then writes a bunch of stuff saying it's down.
If I type hosted-engine --vm-start on one of the hosts (Any), it just
starts and gets back to business.
hosted-engine --vm-status result :
ovirt_hosted_engine_ha.lib.exceptions.RequestError: Failed to set storage

Thanks for your input, and even if it's a storage problem, if it's to
happen, how can I force it to restart the engine?
At first I tought it was a split-brain issue so I added a 3rd host but I
still have the same problem.

Hi,
We have a 3 hosted-engine nodes setup using 2 NFS3 shares on which the
engine keeps crashing every few days.
Looking at VDSM logs, it looks like a storage problem but I'm wondering
why don't they restart the engine?
