I recently had a Proxmox node I was using as a NAS fail catastrophically. Not surprising as it was repurposed 12 year old desktop. I was able to salvage my data drive, but the boot drive was toast. Looks like the sata controller went out and fried the SSD I was using as the boot drive. This system was running TurnKey FileServer as a LXC with the media storage on a subvol on a ZFS storage pool.
My new system is based on OpenMediaVault and I’m am happy with it, but I’m hitting my head against a brick wall trying to get it to mount the ZFS drive from the old system. I tried installing ZFS using the instructions here as OMV is based on Debian but haven’t had any luck so far.
While this post is in support of a self-hosting platform, the request itself is storage-related. I would recommend that you reach out to https://lemmy.world/c/zfs or https://discourse.practicalzfs.com/.
