and I do agree with that, I just don't think this is one of those situations.
disk corruption on disk isn't something that a reboot persay will fix.
if we have the ability to disable a filesystem and continue running,
an operator could unmount the filesystem, copy it to different media,
run fsck, mount it again and keep going. I've done this myself with
vxfs at work and it's really slick when it works.
