Trouble making cluster

[alessio]

Hi all,

I've one server proxmox1 in production e a new one (proxmox2) just installed.
I'd like to create a cluster, but something gone wrong.

1) When I created the cluster all conf files about vm machines were lost.
2) I was able to recreate vm config files but now if i try to change some parameter i recive error:
"unable to open file '/etc/pve/nodes/proxmox1/qemu-server/100.conf.tmp.422047' - Device or resource busy (500)"
3) Now I'd like to remove cluster but how? Why do I receive stranges messages if I try to remove one node? (if it's up or down there is no difference)

root@proxmox1:/etc/init.d# pvecm delnode proxmox2
I/O error : Resource busy
I/O error : Resource busy
ccs_tool: Error writing new config file /etc/pve/cluster.conf

Please help me!

"proxmox1" server is in production and now I fear that if I restart it may be that no vm will reboot

Hi,
you lost the quorum in your cluster und than /etc/pve is read only.

To get the quorum back set the expected votes to one: "pvecm expected 1". After that you can remove the cluster-stuff - but if you wan't to use an cluster you should build/fixed the cluster...

Thanks!
With your help and restarting PVECluster I was able to change configuration
