We have a 3 node HA Proxmox Hyperviser cluster with ceph.

One of the nodes (third node) has a problem and seen offline in the cluster. We would like to examine the 3rd node. In order to do so we disconnect it from the cluster but this causes problem with the working two nodes and we cannot reach the VM's which work on the 1st and the 2nd node.

Any advice appreciated.
 
Hello, could yo be more precise on what do you mean by "disconnect it from the cluster"?
 
Hello Maximiliano,
For the Ceph we have in each node a dual port 40Gb card and and bonded those interfaces. All nodes are connected to each other.
Node 3 will not boot. If I reboot this node the other working VM on the other two nodes are failing. If I unplug the two 40Gb DAC Cables they also stop.
