Cluster question

[strix]

Hello,

i have some questions about proxmox cluster.

We have one cluster with two nodes, node3 and node1. Node3 is the master. I have already create the cluster but after that i try to join node1... but unfortunately node3 has problem.

I'am recieving "error: checksum verification failed. Entering rescue mode.., grub rescue>"

What can i do now? Should i format node3 ? And how can i join the cluster again ?

Please advice

Thanks

We have one cluster with two nodes, node3 and node1.

You need three nodes (at least quorum) for a cluster to work properly.

Node3 is the master.

There is no master in PVE.

What can i do now?

So you have a cluster of two nodes and one broke, so that you've ended up having only one node in cluster?

Hey LnxBil

Yes only the one node working right now.

We created the cluster at srv#1 first of all. Srv#1 has 10 VM on.
We also have srv#2 with 30 VM but unfortunatelly he can't join the cluster because of VM's.
And last of all we try to join srv#3 on cluster, srv#3 has no VM's on. After that we get the message about "grub and rescure mode".


Srv#2 with 30 VM's on can join somewhy the cluster or not ?

Only "empty" nodes can join. One way to get it to work (please test beforehand) is to move the configs out of the way so that it seems that there are no VMs, join and move the files back. I'm not sure if this works with running VMs, but it'll work with shutdown VMs.
