Good afternoon.
There are two PVE clusters and I need to move the node from one cluster to another. Please tell me how to implement this without reinstalling the OS on the node. PVE version: pve-manager / 6.2-4 / 9824574a
 
Hi,

check:
https://pve.proxmox.com/pve-docs/chapter-pvecm.html#pvecm_separate_node_without_reinstall

For separation, then you need to re-add to the other cluster, but note that you need to back up the guest configurations /etc/pve as a node cannot have any guests when joining a cluster and if one uses the force flag they'll be dropped. Disk entries in the guest configurations may also need adaption for a changed storage id.

The simplest here would be to backup all guests that would need to be moved too and just restore them after joining again.
 
Good afternoon.
Thanks for the answer, but when I try to add a node, the following is displayed:
can't create shared ssh key database ssh '/ etc / pve / priv / authorized_keys'
(re) generate node files
generate a new peer certificate
unable to create directory '/ etc / pve / nodes' - access denied
