One important thing I forgot. I copied these files by using cp -R on a big
tree. Afterwards I did a diff and saw quite a few files were not exactly
the same as their original. I removed the new tree and recopied. This
time around I did not get the same listing from diff and the corruption was
to different files.
I tried copying the original tree to a dfferent, non-raid, filesystem and
all files were the same as their original.
I also manually used cp to copy about 10 or 12 of the corrupted files from
the original tree to the RAID filesystem. After this, the files that I
copied did not differ from the originals. It seems that files become
corrupted under a heavy load either by the RAID5 daemon or in hardware.
