Hi!

I've removed a node from our testcluster via "pvecm delnode ..." and reinstalled that node.
When re-adding that node (with the same name) via "pvecm add ..." I get following errors:

Code:
root@node2:/etc/pve/nodes# pvecm add nodename -force
detected the following error(s):
* authentication key '/etc/corosync/authkey' already exists
* cluster config '/etc/pve/corosync.conf' already exists
* this host already contains virtual guests
* corosync is already running, is this node already in a cluster?!
Please enter superuser (root) password for 'nodename':
                                                        Password for root@nodename: *******

500 invalid corosync config: unable to read config version

I fear that I missed to migrate a Test-VM from that node before deleting it - so some configs still remain.
Any hint where to look?
 
you have to run 'pvecm add ...' on the node which is not currently in the cluster
