Any chance of reverting to a 1.9 cluster architecture?

[Scott Alden]

I've been trying to setup a brand new cluster on 2.1 (2 separate occasions) without any success. I can get the nodes to initially see each other, and give statuses, and then about 3-5 minutes in, one of them fails giving lots of corosync errors and then shuts down or crashes cman.

I *really* love Proxmox and would like to continue using it going forward - but the new cluster management is hard to debug and troubleshoot. Is there any chance of using the older 1.9 cluster management or is that out of the question?

I've verified that my switch supports multicast, the clusters know each other via DNS. I've followed the sparse setup instructions *exactly* and I still can't get it to work. I've looked at many of the older messages on this forum that seem to go nowhere with actually helping figure out the multitude of problems.

Does anyone actually have a multiple server cluster running on 2.1?

The new cluster setup is far better than the old way.
I run multiple 2.1 clusters, the largest has 17 nodes in it.

The only time I ever had issues was due to my /etc/hosts file being messed up, once I fixed it my problem went away.
The hostname in /etc/hosts dictates what interface is used for cluster communications if that is different than the interface where your DNS for each node points that could be part of your problem.

If you post some logs files and a description of the problems someone here in the forums is likely to help you.
