Hello,

I’ve upgraded my Dell M1000 blade centre to Proxmox 4.1. The upgrade seems to 
go fine, however I can’t seem to have all 4 nodes connected at once.  It seems 
to work for a short time then then one node will disappear,  I can SSH to it 
just fine, and have to restart corosync and pve-cluster and it will join again, 
however shortly later another node will disappear.

Finally a node crashes and restarts. There is nothing present in the syslogs as 
to why this node cashed.

I’ve spent 2 days fighting with this to try and resolve it.  This was working 
just fine on 3.x.

Please can someone help here I’m pulling my hair out trying to get this 
working, and I don’t have much left!

Cheers,
—Guy
