You can use the /dev/disk/by-XYZ device links.

Subject: [PVE-User] Quorom disk on different devices

Hi list!

I have set up a two node Proxmox cluster on two Dell servers with DRBD. Works well, but I just realized
that I need a quorum disk for the HA setup. I created an iSCSI qdisk as per the FAQ (http://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster#Configuring_Fencing)
but I ran into a problem. For some reason the first server had one extra disk device (floppy, maybe virtual floppy/USB) so now
the iSCSI disk is known as /dev/sde on the first server and /dev/sdd on the second server.

Since the cluster config file is global I guess this will be a problem when defining the quorum disk?
Do I need to start creating udev rules for the iSCSI LUN to persist the naming on both hosts, or
can I cheat in some way? Maybe it would be enough to remove the "floppy" device link /dev/sdd on the first
host and try to re-create the iSCSI target?

PVE Version:
pve-manager/3.1-3/dc0e9b0e (running kernel: 2.6.32-22-pve)
Hardware: 2 * Dell  T620

Best regards
