As far as I know, Proxmox does not need 3 nodes and/or a quorum, and
the
LINSTOR controller does not care either.
Hello Robert,
By default, Proxmox needs the quorum to work correctly in cluster but
can work very well with 2 nodes by setting the corosync.conf.
To activate the proxmox HA, the minimum required is 3 nodes.
You confirm that the linstor / drbd operation is entirely possible with
2 nodes. Perfect.
In my case, I do not necessarily look for high availability of the
controller from the moment when manual recovery is possible.
And so, I do not understand why, since one of the 2 nodes is stopped
(even the non-controller node), my test vm can not restart once stopped
an this error appears :
TASK ERROR: command 'drbdsetup wait-connect-resource vm-900-disk-1'
failed: got timeout
It is very disturbing since on the other hand the other tests give
satisfactions (migration of vm, resize disk or moving...) and the
information reported by Linstor seem good.

br,

I had followed this very good documentation to install my model except
for setting high availability of course, but I do not see where my error
is and I have no additional information in the logs.
Would you have an idea of what I would have forgotten or a track to look
more precisely at the source of the problem ?
Thank you Robert,
Greb
