If you find the remount-ro in your fstab, and you are running ext2 and a
2.4 kernel, you can switch over to an ext3 filesystem in a couple of
minutes.
As root, run `tune2fs -J [filesystem]` on your partitions, and you'll
magically have a journaling ext3 filesystem. There is one gotcha - because
ext3 is backwards compatible with ext2, you need to specify ext3 in your
fstab. Otherwise the filesystem is mounted as an ext2 system.
I use ext3 a lot, and don't have any troubles with the occasional power
outage. (However I don't use mySQL much either - just to play with.) ext3
is also nice as tools such as boot floppies or rescue CDs that don't know
about ext3 will see your file system as a normal ext2 system.
Cheers,
James
