After upgrading my Unraid server to version 7.1.2, I encountered an issue where my ZFS pools (orbit and zulu) are online and healthy (as confirmed by zpool status), but the Unraid GUI shows them as “Not installed”. This issue started happening after the kernel update that came with Unraid 7.1.2.

I’ve already tried several troubleshooting steps, but the issue persists.

Troubleshooting Steps Taken:

1. Confirmed ZFS Pool Health:

   • Both pools (orbit and zulu) are ONLINE with no errors, confirmed by zpool status -v.

2. Checked ZFS Module:

   • The ZFS module is correctly loaded on the system, as confirmed by lsmod.

3. Permissions for zpool.cache:

   • I copied the zpool.cache file to /boot/config/zpool.cache and ensured correct permissions (chmod 644), then rebooted the system, but the pools are still showing as "Not installed" in the GUI.

4. Nginx Restarted:

   • I restarted the Nginx server to clear any potential stale data, but the issue persists.

5. Reboots:

   • The issue persists across multiple reboots, with the pools appearing as "Not installed" in the GUI despite being healthy and accessible via the command line.

Current Behavior:

• Pools (orbit and zulu) are shown as “Not installed” in the Unraid GUI, despite being ONLINE and healthy (both pools are accessible and have datasets such as dockdata and plex_bot mounted).

• Datasets (e.g., dockdata, plex_bot) within the pools are listed and accessible, but the GUI does not properly display the pools themselves as "installed."

• The issue is persistent and occurs only after the upgrade to Unraid 7.1.2.

Export both pools using the CLI zpool export <pool name>, click on both pools on main and select "remove pool", add new ones with the same name and correct number of slots, assign the devices for each pool, leave the filesystem set to auto, start the array, post new diags.

Worked, Thank you!
