Recently I received email notification on this:
Device: /dev/sdd [SAT], Self-Test Log error count increased from 0 to 1.
Output of
sudo smartctl -x /dev/sdd gives snipped below:
Output of
sudo smartctl -a /dev/sdd gives snipped below:
Is it advisable to replace this disk?
How long have you had this disk? Still under warranty? Does running a manual short selftest also result in an error?
If so, yes, I wouldn’t take any chances. I’d replace the disk and resilver. The sooner, the better.
That’s a meme right there:
Long test fails, short test passes. Not sure if you should run another long test or just replace the disk. 
Smart test fails. In warranty. Replace. Not hard.
Outside of warranty. Now you have decisions to make.
…
Surely there’s a koan or haiku in there…
I’ll one up you on that:
Long test fails.
Short test passes.
Scrub passes.
Drive is outside of warranty.
Manufacturing centers get flooded.
Price of harddrives sky-rocket.
WHAT DO YOU DO?
Hurry. You have 60 seconds to answer the question for the million dollar prize!
@Kasazn if the data is irreplaceable (even if you have a recent, working backup), I’d definitely err on the side of replacing the drive if you can afford it.
I zeroed the disk and reran the long. It passed. And all pendings went away.
It finished burn in again.
It’s about to go back in service. Just 5 years old 
But it’s on its final warning. Next stop is the bin.
Good actions, good decision IMO.
