Thanks, I agree bad idea to execute virsh command without knowing vdsm and engine.

Is their any plan in ovirt to support drbd + Pacemaker ?

When you come from libvirt and you know what to do, you might not want to find/read a dedicated documentation for such a little query.


yes, sure, for read-only
but for any modification, no matter how minimal, it’s almost always needed to inform vdsm/engine to know about it to prevent corner cases, misdetections, etc...

Use at your own risks:

vdsm@ovirt:shibboleth

But, you may unsynchronize your host HW with engine database.


it is almost always a bad idea to do that
hooks are exactly for the cases like below, just in a cleaner way

If you only need read access then you need to supply -r as an additional
argument.

Why do you need virsh because that will only give you the info on that
host, using ovirt-shell gives you the info for all hosts.
