Hello,
I am currently testing LINSTOR/DRBD with Proxmox 7.3 on a three nodes
cluster with:
Nodes A and B:
* DRBD over ZFS
* LINSTOR controller and satellite
* DRBD reactor for HA setup (followed the guide at
https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-linstor_ha)
Node C:
* DRBD diskless
* LINSTOR satellite
Now, if I do the following:
* All nodes UP and a VM with Proxmox HA enabled and stored on DRBD,
running on node B.
* Stop Node A.
* Stop Node B.
* Start again Node B.
* The Proxmox GUI of Node B is no longer accessible until I restart
Node B. And the VM doesn't start.
In the logs of Node B i can see "pvestatd[1990]: could not connect to
any LINSTOR controller at
/usr/share/perl5/PVE/Storage/Custom/LINSTORPlugin.pm line 214."
With drbdmon I can see "QUORUM LOST" on all resources.
I understand the reason that LINSTOR/DRBD won't let access to DRBD
ressources, since it can't really have quorum on the resources (should I
transform the diskless node into one with just enough storage for the
linstor_db?). But I don't think it is normal that when there is no
LINSTOR/DRBD quorum (but Proxmox quorum), you can't access the GUI of
some nodes (for example, for running VMs located on another storage).
Thank you for any help.
Regards,
Nicolas.
