NAS Migration Planning Help

Well the time has come again to update my NAS. It’s currently on TrueNAS Core V13. This time I need to actually throw good parts on it and not just stuff from the spare parts bin.

Requirements:

  • Migrate away from TrueNAS CORE (probably to SCALE)
  • Move to new CPU with ECC memory.
  • Move from direct MB SATA to IT-Mode SAS controller card.

Current config is 6 x 4TB HDDs in RAID-Z2 at ~80% capacity. Drives are WDC WD40EFZX-68AWUN0 at ~2800hours so they have a fare amount of life left. I’d like to keep them going as I’m paying to update everything else.

So here’s the idea’s I’ve been tossing about:

  1. Migrate HDD to new PC, import ZFS pool, clean pool of CORE junk and import to scale. (Fiscal cost - none, mental cost - lots, no space expansion)
  2. Backup to 14TB HDD or Tape, wipe drives, new pool (old + new drives), transfer (~$300, nice even clean pool)
  3. Create a new pool on new PC with >= current capacity, transfer data, transfer old disks, create a new VDEV with old disks and add to new pool. (~$500, double space expansion, gross uneven pool)

So there’s a million options depending on how much cash I throw at this. What do you guys tend to do?

only 120 days of uptime?
I hit that per drive every month

For production we
-deploy new NAS
-transfer data from old NAS to new NAS
-Repurpose old NAS to backup duty
2 is 1, 1 is none and so on…
