[PVE-User] Quorom disk on different devices

Thank you Dietmar.

However I just realized that the cluster config refers to the quorum disk by label, not by device.
So maybe this wasn't my problem in the first place.

Here's the cluster config I'm trying to apply:

<?xml version="1.0"?>
<cluster name="sthlm-bb" config_version="3">


<cman expected_votes="3" keyfile="/var/lib/pve-cluster/corosync.authkey"/>
  <quorumd votes="1" allow_kill="0" interval="1" label="proxmox1_qdisk" tko="10"/>
  <totem token="54000"/>

  <clusternodes>
  <clusternode name="beast" votes="1" nodeid="1"/>
  <clusternode name="beauty" votes="1" nodeid="2"/></clusternodes>

</cluster>


Now I'm not really sure what the status is of my cluster. I'm stuck at the line on the wiki that says
"
Verify that rgmanager is running, if not, start it"

/etc/init.d/rgemanager start
doesn't work:
root at beast:/var/log# /etc/init.d/rgmanager status
rgmanager is stopped

My /var/log/daemon.log is filled with 
Oct  2 10:55:11 beast pmxcfs[635625]: [status] crit: cpg_send_message failed: 9

My problem seems to be that rgmanager won't start, is this due to some misconfig of the qdisk?
I can't find the error log from the rgmanager startup

Here's the info about the qdisk from both nodes:
root at beast:/var/log# mkqdisk -f proxmox1_qdisk
mkqdisk v1364188437

Any idea what I have done wrong?

Thanks,

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
Johan Wikström
