Our 3 year old, 120TB/30-drive(RAID Z2), NAS recently started showing critical alerts for multiple drives. We've had single drives(5) develop 8-10 bad sectors over the years, and replaced them under warranty. These drives are getting long in the tooth, so this is no surprise. I'm just wondering if any of these errors are worthy of concern?

CRITICAL: April 18, 2018, 4:45 p.m. - Device: /dev/da11 [SAT], 2 Currently unreadable (pending) sectors
CRITICAL: April 18, 2018, 4:45 p.m. - Device: /dev/da11 [SAT], 1 Offline uncorrectable sectors
CRITICAL: April 19, 2018, 4:55 p.m. - Device: /dev/da11 [SAT], Self-Test Log error count increased from 0 to 1
CRITICAL: April 20, 2018, 3:54 p.m. - Device: /dev/da11 [SAT], Self-Test Log error count increased from 1 to 2

I have short and long SMART tests set to once a week, and bi-weekly, respectively. The most recent "freenas.local daily run output" returned:
Checking status of gmirror(8) devices:

mirror/swap4 COMPLETE da21p1 (ACTIVE)
da20p1 (ACTIVE)

Scrub runs with no errors or repairs.

My concern is about the "DEGRADED da26p1" drive. Although, its SMART test finds no errors. While the other drives do

The drives with errors need to be replaced.
Three years is not, "long in the tooth," for those drives. They should last 5 years easily. I have a server at work with 60 of them. They do have a higher failure rate than the 6TB Red Pro drives in one of the other servers. Out of the 60 x 4TB drives, I have had to replace 9; where the 60 x 6TB drive server has only lost 4 drives.

Ideally, you want to replace a faulty drive before you get data errors that the scrub would need to try and fix. Your goal is to never have a scrub show an error.
You run SMART testing to find the bad drive that might cause an error, so you can replace it before the damage is done.

The gmirror error will go away with a reboot. That's the swap space and it is destroyed at shutdown and created during boot up.

da26 looks fine.
da11, da7 should be replaced as soon as possible.
da27 should be fine for now, monitor.

Any reason for hourly shorts SMART tests? That's overkill, make sure extended tests are regularly scheduled also.

I have short and long SMART tests set to once a week, and bi-weekly, respectively.

I think your schedule is not setup correctly because as @Johnnie Black pointed out, your short tests are running every hour, based on the log you showed. I usually run my short test daily after business hours and schedule the long test for the weekend.

Since you mentioned the drives were getting old, are you looking to replace them with something larger / newer? The underlying server should still be fine for another 5 years easily as the important parts of the technology have not changed significantly from what you already have.

Thanks for the replies, I really appreciate it.

Chris, it’s (partially) reassuring to know we aren’t the only ones having an unusually high number of these drives turn up errors. As I said, we had ~5 replaced already, and another two need to go now. That’s a >20% error rate. Luckily, I’ve got a couple of spares around and all of ours have 5 year warranty replacement. [RMA for da11 today]

The hourly SMART test setting was a brainfart, on my part. I’ll set it to run at 4am, nightly.
