I have here another question about the new storage modell.
I use here 4 server with proxmox. Two of them have already manually configured drbd devices. I want to convert it now to the proxmox implementation.
I disconnected the drbd devces and created the drbd devices from scratch on one of the two servers and also the LVM volumes.
I created the kvm machine, attached the storage, created the virtual disk, all worked flawless without problems. starting the machine with a startup disk works and shows all disks available.
When I now enter the proxmox web gui and go into the hardware section of any kvm machine (regardless linux, windows) I get the following error:
12555]ERR: 24: Error in Perl code: command '/sbin/vgchange -aly drbdvg1' failed with exit code 5
I would assume this error is because the kvm machine resides on different server, which has no volume group because I did not create it already ?
In this case I would get this error still when both drbd nodes are configured but the other server don't have the volume group configured (and don't need it, because drbd replicates only between two nodes typically) ?
 
Sorry, but drbd currently only works with 2 node clusters - else you get above error messages because of the reason you pointed out.

In future, we plan to add a additional option to the storage configuration, to tell on which nodes a storage is available.
