[SOLVED] Is it possible to mount a ZFS drive in OpenMediaVault? (lemmy.sdf.org)

Original Post:

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:

  1. Download and install OMV Extras
  2. OMV's web admin panel, go to System -> Plugins and install the Kernel Plugin
  3. 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.
  4. Reboot
  5. Go back to the web panel, System -> Plugins and install the plugin openmediavault-zfs.
  6. 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.

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/.

!zfs@lemmy.world has under 300 sub's, I feel like this is a fine sub to post it in until niche sub's get an active user base

I’ve only ever tinkered with openmediavault, so I’m by no means an expert, but there is a ZFS plugin available. Here’s a forum post that may help: https://forum.openmediavault.org/index.php?thread/7633-howto-instal-zfs-plugin-use-zfs-on-omv/
