Cluster Disbanded

[vigorianer]

Due to a backup error, I destroyed the hard drive on one of my three cluster computers. Now the second PC is also causing problems and I can't use my cluster properly.I deleted the cluster on the main PC and am rebuilding it.My problem is that I was able to delete two connected PCs from the cluster, but a remnant still exists.How can I fix this? PVE 1 is running fine again so far.

Error message:hostname lookup 'pve2' failed - failed to get address info for: pve2: Name or service not known (500)PVE 8.3.5

you need to remove nodes from datacenter.
https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node

after that you need to remove unused SSH keys both from root and nodes folder.

then re-install and re-join nodes.

as long as you have backups, may more easy to complete re-install the whole cluster.
