That's good, I guess, but I fell into what seems to be a problem yesterday.
I've mentioned before that I have 8 disks in an array. 7 of which
belong to it (degraded), and one doesn't. That outsider disk had bad
sectors. I wrote zeros to the disk yesterday and both Pending and
Offline counts have been reset, but Reallocation count didn't
increase. I did run an immediate offline smartd test after zeroing the
disk...
Does that make sense?!
