ZFS errors / SMART errors Asking for advice

CmdrDeLiver · Jul 13, 2023

I'm receiving the following from my root pool. It's a 3 drive mirror with lightly used drives. After each scrub, the errors are reset. I'm never seeing more than a single cksum error between monthly scrubs. Data is in offsite and local backups so I'm not worried about it. I looked as the SMART report for each drive and some of the numbers __feel__ bad. I've learned not to take a SMART report at face value as raw values are often not what we feel like they should represent. I'd appreciate some feedback on the reports below from someone who understands what they mean. The drives are 2 years 3 months old and should still be under warranty. If there's a failure I'd like to catch it before that runs out.

Thanks in advance!

Mike

ha. there's no way to do that. they'll fail when they'll fail. it can be in the next 5 minutes. it could be in 10 years. As long as you dont let them overheat or rattle them when running there's not much you can do to them.
