As I understand it, reinstall is recommended for both cases. I don't think
trying otherwise is worth it, multiple issues can arise.

Hi Eneko,

Appreciate the feedback, that is precisely what I did and didn't have any
issues.

Thanks.

i‘m curious which issues can arise and whats so difficult in removing and re-joining.

 i would find it useful to to  migrate hosts between cluster, ad for now there is no easy or quick method to migrate virtual machines between clusters.

[PVE-User] Removing Node from Cluster A and adding to Cluster B

[JR Richardson]

Hey Folks,

 

Quick question I hope, I have two productions cluster running PVE6 and
working fine, 13 node in one, 4 in another. Bother clusters have separate
switch VLANs and IP space so they are logically isolated. I have a need to
shift a couple of nodes from my larger cluster to my smaller cluster.

 

My question is after I remove the nodes from one cluster, I'm reading best
practice is to re-install PVE from scratch before adding back to the
cluster. But this is to add it back to the same cluster or is this best
practice regardless of adding to new cluster as well?

 

Thanks.

 

JR
