Cluster with one Node - Cant change Hardware

[sunghost]

I set up an 2 node cluster to move all vm from the old node to the new node which worked well. after that i shut down the old node and wanted to change the ram of one vm on the new node. But i get the error

unable to open file '/etc/pve/nodes/XXX/qemu-server/101.conf.tmp.2126' - Permission denied (500)

I read that this could be normal in an cluster with an faulty node. is that right or what could i do?

You you not have quorum (only one node online)? Force with

# pvecm expected 1

But make sure the other node is offline when you do that.

Hello Dietmar,

this works for me. Thx, but for understanding what means this at all? Tell the Cluster that there is only one node and what are the effects of that?

Is there a way to make this

pvecm expected 1

permanent? Since it solved all of my issues because I also have 2 nodes in my cluster (PVE and PVE-BACKUP) but the backup server is not running 24/7.
