Only notify when unreadable sectors increases

Question

Is there a way to only be notified when the amount of unreadable sectors increases on a certain disk?

The following warning/error was logged by the smartd daemon:
Device: /dev/sdb [SAT], 4 Currently unreadable (pending) sectors

I have been getting this error for quite a while now in my mdadm RAID5 array and the amount of unreadable sectors does not increase. I am only planning to replace the disk when the unreadable sectors increase.

By then, it may be too late! – Michael Hampton Dec 08 '15 at 13:38 — Michael Hampton, Dec 08 '15 at 13:38

Bad sectors mean disk issues. Waiting for the sector count to increase simply doesn't make sense since by that threshold its already gone from 0 to 4, with the next potential jump being all.

Thats what we have RAID - to have redundancy and not be affected by one HDD failing. So it is perfectly reasonable to wait until a disk fails completely, especially if a hot spare is already in. – Diego Sep 03 '18 at 13:07
