Hi all,

I’m running into an issue where my cache/pool devices are no longer visible in the Unraid UI.

• Context:

  • Unraid version: 7.2.4

  • I recently moved the server to a new physical location (same hardware, just relocated)

  • After powering it back on, I started troubleshooting and the pools disappeared from the UI

  • I’m unable to start the array without the pool devices setup correctly

  • When I try to add a pool with the same name as the old one (cache) I get an error saying the pool already exists, though not visible in UI.

• What I’ve done so far:

  • Booted into safe mode

  • Checked /boot/config/ and confirmed:

    • super.dat exists

    • pools/ folder exists

  • Restarted nginx (/etc/rc.d/rc.nginx restart)

  • Rebooted multiple times

  • Accessed Unraid through Safari on iPad, Chrome and Firefox on Windows.

• Current state:

  • /boot/config/pools/ exists

  • super.dat is present

  • However:

    • No pools show up in the UI

    • Even the boot device appears empty in the UI

  • Disks themselves appear to be detected at the system level

• Diagnostics:

  • Attached

Thanks in advance!

Try accessing the GUI from a different browser or device.

Thanks, I’ve tried it with Safari on iPad, Chrome and Firefox on Windows and the issue remains.

In that case, my recommendation would be to redo the flash drive, backup the current one first and then recreate it using the USB tool and just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder (\config\plugins\dockerMan\templates-user), if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.
