there are VMs on both hosts.
clean one of them and then you can join it.

 

[nishuo]

vmid does not conflict, why should you clean it up? Any good ideas?

as a precaution it's not allowed to join a cluster when you already have VMs on a node (pve-cluster related issues).

just make a backup of the VMs on one node. transfer the backups somewhere, then clean the node and you'll be able to join.

edit: "clean the node" meaning remove the VMs

i just install 7.0 on new hardware, then want to transfer VM from old (6.4) no new 7.0 : what is the best way ?
thank you

Hi, the easiest way is, Backup and then Restore to the new Cluster.

VM (debian 10 based) are very very slow under proxmox 7.0 ... why ?
perhaps ZFS raidz 8TB is initiate ?
