Recovering VM in another node of cluster

[zimny]

Hi there,

I'm trying to recovery my vm from node failure. I'm not using HA but do replication of disks in my cluster.
After recent failure of one of the nodes I'm trying to recovery my VM to another node.
pr1 is failure node pr2 is working node where I'm connected ssh.

when I trying: mv /etc/pve/nodes/pr1/qemu-server/201.conf /etc/pve/nodes/pr2/
I got:
mv: cannot move '/etc/pve/nodes/pr1/qemu-server/201.conf' to '/etc/pve/nodes/pr2/201.conf': Permission denied
I'm root
And I'm lost
Anyone can give any directions pls?

Hi thanks for your reply,

So Quorum was the issue and manual page in the same time.
I fix by:
pvecm expected 1
and then
mv /etc/pve/nodes/pr1/qemu-server/201.conf /etc/pve/nodes/pr2/qemu-server/
this did a trick
I think this is typo in Proxmox man pages
Also that was only two node cluster so not recommended by Proxmox
Wondering if have the same issues with more then 2 nodes.

sure you can recover that way only with disk replication or share storage

I put my finger in few vendors in the past but only because of price and licensing
Proxmox is my go and recommendations from now always

If you can do better about node removals from cluster or all cluster etc.
I find a lot of mess with knowing hosts certs after removal. Also manual pages are not updated.
But this is easy pessy so thank you for your work
