Hi Guys,

I am using 2 cluster setups as follows,
1. Cluster with 3 Nodes, CEPH storage, SNMP fencing to enable HA for critical VMs.
2. Cluster with 3 Nodes with CEPH shared storage and without SNMP fencing, HA VMs.

pls anyone can help me to join the failed node without reinstalling the PVE in above two diff setups.

a. In 2nd cluster what will happen if one node fails and join back to cluster automatically, what is the procedure to rejoin the cluster without installing the proxmox?

b. In 1st cluster i understood that if any failed node comes to online in the same network the HA resources (VMs) will cause the data corruption in CEPH. To avoid it we are configuring the SNMP fence.

What is procedure/steps to add the failed node without reinstalling the proxmox?
If you want to add the failed node, How can we delete the HA VMs from it without CEPH cluster quorum?
In failed node, is there a way to delete the CEPH VMs & Config.?
If i reinstall the failed node, how to join it to the running CEPH cluster (Monitor, OSD, PG no, Ceph pool)?

Thanks in advance..
