I have two identical servers running the latest version of Proxmox. Each server has 2 NIC's, one for public networking and other for clustering. I have no shared storage yet, but I plan to add it when I reach certain amount of servers.
These two were in a cluster. Cluster was created on a first server (call it PMX1) and the second was added to the cluster (PMX2). Everything worked perfectly until RAID array fall apart on PMX1 node and I had to reinstall it as soon as possible in order to restore virtual instances and services on them.
Now, my PMX1 node has 10 virtual instances (starting from ID 100), and on PMX2 I also have some instances (20 or so with mixed ID's). When I login to PMX2 I still see a PMX1 in a node list but I do not see a list of instances (which is logical).
This is the output of the pvecm status command on PMX2:
I had to reduce Expected Votes number from 2 to 1 in order to create some new instances on PMX2.
So the question is quite simple - is there a way, and how, without any loss (be aware that I cannot reinstall any of these nodes) recreate a cluster and add these two Proxmox nodes or not?
