..I'd do 'tune2fs -j -s 0 /dev/hdb1' to turn off the default
"sparse" option, for ext3fs'es holding important data.
And default 180 days without fsck is much too long, at least
for carrier grade service.

..I advice _against_ this practice, see above, and in
my other posts in this thread.

..consider your options for this fs, is an errors=remount-ro ok,
or does the data value warrant a prompt kernel panic? YMWV.

Scenarios always come in sets of three:
best case, worst case, and just in case.
