Proxmox Container and VM configuration files on ZFS

[macamba]

When I setup my new server:
- I installed Proxmox VE on a fast SSD disk (default partitioning, probably ext4)
- And for ISO's, vm disks, and container disks, and data I created ZFS pool of HDD disks and datasets on the same server.

But how can I put my configuration files, i.e. vm and container configuration also on a ZFS datasetl?

So that in case of a re-install of the host I have all configurations still existing and easily reloaded in the fresh install?

hi,

if you want to have your configurations backed up you can just backup the /etc/pve/ directory or the /var/lib/pve-cluster/config.db (which is the backing database file of the cluster filesystem on /etc/pve/)

if you reinstall you can easily restore the configuration files from that backup.

Thanks Oguz, backup is indeed also a solution. Based on you answer I assume there is no solution to place or redirect /etc/pve and /var/lib/pve-cluster/config.db to a location on the ZFS storage?

you could, but there's really no reason to do it as it won't bring you anything substantial in terms of performance or backup-ability.
in fact, the storage setup (where your zfs storages are listed) is done in /etc/pve/storage.cfg, so moving this file into the ZFS dataset would probably break your system. (besides the million other issues this would cause on your system, as /etc/pve is a fuse filesystem backed by the config.db sqlite)

Thanks again, understand. Definitely not a path to pursue further.
