Nope. Your pending is still at 8, so you've got bad sectors in an area

that your SMART test results don't list the LBA of the first failure.
Disappointing behaviour on the part of the disk. They are within the
1st 10% of the drive however, so it wouldn't surprise me if they were
in an unused portion of the RAID superblock area.
Thanks Brad. So, to theoretically get these sectors remapped so I don't
keep getting errors, I would have to somehow try to write to those
sectors. That's tough given that the LBA's aren't reported as you
mention. Perhaps my best course of action then is to:
No, just use dd to read that device -- it'll bail out with read error
when it hits the trouble spot, which will report the affected sector.
Then you can rewrite it with the appropriate seek= value. (Assuming it
really is in an unused part of the member device.)
So, I got a read error as expected, running (physical sector size of sda
is 4096):
dd if=/dev/sda of=/dev/null bs=4096
Is there some way to tell whether this sector is considered to be in
use? Not sure what the effect of rewriting it might be if it is...
If it's safe, I'd run:
dd if=/dev/zero of=/dev/sda seek=5857843312 count=1 bs=4096
Perhaps the way to go is to write to it, and then run checkarray again?
Thanks,
Allie
