I lost the cluster communication again.
I have been using Proxmox since version 1, and this is the first time
It bothers me so much!
- All the 10 nodes have the same version
(pve-manager/5.2-9/4b30e8f9 (running kernel: 4.13.13-2-pve))
- All they have the same date / time (It is one of the causes It could
lose the communication)
- The environment is ident (No new switch, no new server)
And why all these nodes lost the communication at the same time ? If
they are 10 at least 5 have to be with problems to lost the quorum and
then the connection. Is it true?
I think it is something related to this proxmox version.
What to do ?
That happened to me a few versions back on a 3 node cluster. I had to
switch heartbeat from multicast to unicast to keep things stable. There
were no changes in any of my equipment when this happened.
