TrueNAS SCALE Disk Pool not showing

Update on my truenas0 pool issue:

I followed both of your suggestions as closely as possible.

Hardware & Diagnostics:

  • Motherboard: BKHD-1264-NAS (Intel N100)

  • Drives: 4× HGST HUS726040ALE614 4TB connected via onboard JMB585 SATA controller + hot-swap backplane

  • Pool layout: Single RAIDZ1 vdev (4 drives)

  • TrueNAS SCALE version: 24.10.2 (Electric Eel)

Diagnostics performed:

  • Long SMART tests on all 4 drives → All PASSED

  • Memtest86 → 4 full passes with 0 errors (the Memtest86 defaulted to 4 passes only I didn’t think I needed to run it again)

  • CPU + RAM stress test (stress-ng, 30 minutes) → Passed (6/6 tests passed, CPU temp stayed ~77-78°C)

I also ran the sudo zpool import command and got the following output:

pool: truenas0
id: 14434060225059854200
state: FAULTED
status: The pool metadata is corrupted.
action: The pool cannot be imported due to damaged devices or data.
The pool may be active on another system, but can be imported using
the ‘-f’ flag.
