I don't have any resources, but my understanding is that LBAsect is
the logical sector of the block device (i.e, the raid array), while
sector is the physical sector of disk. LBAsect looks
suspicious...referencing a sector that is somewhere around the 91
petabytes address. You didn't mention how large the disks are, but
even there they are requesting a sector that is about 220G from the
beginning of the disk, and returning that no such sector exists
(SectorIdNotFound).
So my guess is that your filesystem is getting confused under load,
and trying to access stuff that is beyond the end of your raid array.
So, which fs and kernel version?
