Should I be worried about this error message?

I’ve got a bunch of Western Digital Red HDDs in a zpool. It’s been running reliably for a long time, but recently I’ve noticed the occasional “hiccup” when reading files via SAMBA. It’ll hang briefly (5-10 seconds), and then return to normal operation.

All HDDs pass SMART tests. The last zpool scrub found no errors, and zpool status shows no errors.

I found the following in /var/log/messages. Should I be concerned that the da3 disk is failing?

Nothing obvious however this value is quite high. Might be worth comparing this value with your other drives to see if it’s isolated or not.

5

Other drives are similar.

  • /dev/da2: 577763
  • /dev/da3: 579341
  • /dev/da4: 577503
  • /dev/da5: 577608
  • /dev/da6: 577846

Does that imply the drives are nearing end-of-life?

6

It’s normally a sign the heads are aggressively parking themselves which overtime will reduce their life expectancy.

But this is separate to your main issue. It appears da3 is sometimes losing communication. What hardware are you running and how are the drives connected to the mobo?

7

There are 2x LSI 9311-8i (Flashed to IT Mode).

Supermicro SuperStorage 6048R-E1CR36N W/ X10DRi-T4+, which is a 36-bay 4U enclosure.

8

Take a look at this thread regarding the aggressive head parking.

9

Do you know what firmware they’re running?

Thank you for all the Q&A and all the info. Looks like I’ve got some reading to do.
