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.
Solved:
- Download and install OMV Extras
- OMV’s web admin panel, go to System -> Plugins and install the Kernel Plugin
- Go to System -> Kernel and click the blue icon that says Proxmox (looks like a box with a down arrow as of Jan 2025) and install the latest Proxmox kernel from the drop down menu.
- Reboot
- Go back to the web panel, System -> Plugins and install the plugin
openmediavault-zfs. - Go to Storage -> zfs -> Pools and click on the blue icon Tools -> Import Pool. From here you can import all existing zfs pools or a single pool.
ZFS comes from a plugin in OMV. You have to install omv-extras first, then install the plugin omvextras-zfs. Make sure you also install the proxmox kernel and reboot the server before installing zfs.
Thank you!
