The issue with the NAS HDD could be resolved, but it may also indicate the drive is nearing failure.
The issue with the NAS HDD could be resolved, but it may also indicate the drive is nearing failure.
You're seeing SMART test warnings on your NAS despite HexOS not displaying them. Your datapool setup uses RAIDZ1 with three drives and 7.28 TiB per drive, meaning a single failure won't stop everything. Consider checking the RAID status, ensuring all drives are healthy, and reviewing any recent changes. If unsure, you might want to consult the documentation or reach out to support for further guidance.
Use a tool like WD or Seagate to examine the drive and view its current status.
IIRC from the truenas shell you can pull the SMART values with: smartctl -a *diskidhere* So: something like: smartctl -a /dev/sdca (<--or whatever disk it was) I know I have notes about this at home (so I can check this), as I always run the long tests every time I stick a new drive in my NAS to verify it's good. Odds are high though the drive needs replaced once it fails the extended / long test. I wouldn't trust it.
