Good advice.

More good advice.  I ran one on the ATARAID and one of the LVMs.  I'll
run one on the other LVMs.  Actually, I'll run one on ALL the
filesystems to see if they are still clean or of something is scattering
data all over the place.

Uhm, it was "chattr -i" that I tried.  The latest version of Outlook for
Windows (shoot me, I know!) thinks it's so smart so it capitalizes the
first letter of every new sentence.

If tune2fs -v is any indication, I'm running v1.25.

This is still a very annoying problem.  chattr -i <-- I corrected it
this time :)  Doesn't make the files or directories deletable.  Any
other ideas?
