Quorum Disk Configuration for Two-node Clusters

[jag3773]

Hello, I've added a section to the two-node cluster configuration notes concerning setting up a quorum disk backed by iSCSI. Check it out at: http://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster

I would appreciate feedback if anyone attempts this. We have used this procedure internally, but who knows what you may find

Very useful tutorial! Thanks to share it but i have question, if we shutdown the 3' server (the iSCSI server for quorum lun) how is managed from the two proxmox node?
Sorry for my stupid question but I cant test this configuration.
Sincerely

Dimi,

I'm not sure that I understand your question. If you read through the wiki page again you'll see that I note

In essence, any one of your three devices will be able to be down at a given time, one of your two nodes, or your block device. Having two down at the same time could cause problems.

The cluster should act very similar to a 3 node cluster in that it is expecting 3 votes total, but 2 votes is enough to establish a quorum. So you can shutdown any one of the 3, but if you shutdown 2 then you may have problems.
