[SOLVED] Cluster join issue

[AxelTwin]

Hi everybody,

I tried to join a third node to my cluster today. The node is visible in the cluster but with a red cross.
I can ssh login to the new node from the cluster GUI but it keeps asking for password.

Can someone enlight me ?

ok, they have to be on the same network...

 

[fabian]

well, they don't have to be (they just need to be able to talk to each other via UDP reliably over low-latency stable links, which is easier the less hops/hardware is involved).

ok, thanks for the hint.
I am trying to connect the third node which is a local one behind nat, to the cloud cluster.
I need to get all the vms back from this cloud cluster to the local node and then shutdown the cloud cluster
What would be the the easiest/fastest scenario ?
Each of the cluster nodes are also PBS servers, is there a way to just connect the local node to the PBS and restore vms backups ?

 

[AxelTwin]

ok, found the solution.
I connected the pbs server to the local node's storage and restored from there.
Thanks !

 

[fabian]

yeah, backup and restore is the way to go in such a scenario!
