Deleted files under /etc/pve/nodes,is there any other way to recover them?

[eden]

I accidentally deleted files under /etc/pve/nodes, resulting in no virtual machines being visible in pve. I have tried testdisk and extundelete, but neither can recover the files. The qm related commands also cannot find the nodes related configuration files and cannot be used. Is there any other way to recover them?

restore from backup.

Those aren't normal files. Its the content of a SQLite DB mounted to /etc/pve via fuse as pmxcfs: https://pve.proxmox.com/wiki/Proxmox_Cluster_File_System_(pmxcfs)#_recovery

Without a backup of your config.db or /etc/pve folder you are out of luck. Always have a recent backup of the /etc folder. You can for example back it up to your PBs using the proxmox-backup-client.

In case you run a cluster you might get a copy of those files from there. And PBS/VZDump backups of your guests at least should contain the firewall and VM/LXC configs of those guests.

Except, don't use PBS to back up PBS. Obv.

It is indeed unfortunate that I didn't back up the config.db and /etc/pve directory.
