Quorum disk in a 8-nodes HA cluster ?

[x3w]

Hi everyone,

Is it possible to configure a quorum disk in a 8-nodes HA cluster (as described for 2 nodes in http://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster) ?
Would you say it's a good idea for keeping the cluster quorate when loosing half of the nodes (problem in a computer room) ?

Thanks for your suggestions or solutions you experienced.

It it possible (but I never used it for cluster with more than 4 nodes).

Is there other solutions, like settings expected vote to 4 (instead of 8) ?
Regards

You probably miss-understood the quorum concept? On 8 nodes, expected votes is 5.

On 8 nodes, expected votes is 5.

In my case it is 8, but I understand what you meant .

...
Nodes: 8
[B]Expected votes: 8[/B]
Total votes: 8
Node votes: 1
Quorum: 5
...

Anyway, from what I've read, changing the 'expected votes' value won't lower the 'quorum' value (I'll do the test).
So the quorum disk seems the best solution to try for now.
Thanks.
