Hi,
I chose the words "rebuilding a replaced disk" deliberately as I removed
a disk that (according to adaptec's software) had some "media errors"
even though the SMART attributes showed there were no "pending sectors"
or "reallocated sectors", in fact all the SMART attributes were clean.
As I was also using "RAID 6" I did not expect any issues leaving the
filesystem online while rebuilding. Previous to this the RAID had been
running live 24/7 for 0ver three years.

We have a RAID system with file system issues as follows,
50 TB in RAID 6 hosted on an Adaptec 71605 controller using
WD4000FYYZ drives.
Centos 6.7 2.6.32-642.el6.x86_64 : xfsprogs-3.1.1-16.el6
While rebuilding a replaced disk, with the file system online and in
use, the system logs showed multiple entries of;
XFS (sde): Corruption detected. Unmount and run xfs_repair.
Late to the game, I just wanted to remark that I've unfortunately
verified many times that write activity during rebuilds on Adaptec RAID
controllers often creates corruption. I've reported that to Adaptec,
but they don't seem to care much...
