Looking for thoughts/opinions

I have a 5 disc raidz1 array. The volumes are accumulating CKSUM errors - fairly evenly distributed over the discs. I’ve been lazy and let this progress to the point where there are permanent errors in files.

# zpool status -v
  pool: tank
 state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

errors: Permanent errors have been detected in the following files:

        /you/do/not/need/this/level of detail.txt

I’ve done some research and believe (hope) that the cause of these errors is the “domestic” onboard SATA controllers I’m using and I have ordered a LSI SAS3008 9300-8i HBA as an upgrade.

I know I can fix the permanent error by deleting and restoring it and then running a scrub. But, I’m torn - should I scrub now and risk stressing it more on the crappy SATA controllers, or wait until I get the new HBA (in a few weeks - free cheap, slow, shipping)?

    I’d shut it down before it corrupts even more, replace HBA when it arrives and run a scrub to see what’s the damage

      I know that’s the correct response. But, it’s been running like this for many months, maybe even years - as I said in the post, I’ve been lazy. There’s nothing on it that can’t easily be restored, or replaced, and shutting it down would be a PITA.

        There’s always a chance your backups might get corrupted too if you let it continue like that
