I know you can convert an ext3 filesystem to ext4. Can you not do the same ext2 - ext3? Yes, with the -j flag to tune2fs.

The man page says you can even do it to a mounted filesystem, but I'd be more comfortable running tune2fs -j from a live CD or similar. I haven't actually done this since ext3 became the standard many years ago, but I'm pretty sure I converted unmounted partitions. YMMV, naturally, and you might want to sacrifice a live chicken in front of the computer before starting. Couldn't hurt.

I'm not sure why your system needed to be checked for each boot... Boy, my 'little gray cells' need a tonic, too. I've been using ext3 (i.e.with journaling) for so long I can't even remember using ext2. Wasn't it normal in the old days to fsck an ext2 fs with every boot?

And maybe go for a walk :) No, I'm not aware of it *ever* being standard to fsck on every boot. Perhaps you were using a bad distribution? True, Linux does run fsck on every boot, but fsck exits immediately if it determines your filesystem was unmounted cleanly on the last shutdown. It's only if you force a fsck (e.g. with -f or /forcefsck) that it will run fsck on a clean filesystem. And remember, ext2 has *no* journal, so fsck was always very very slow. To run it every time on a reboot would have been so painful that I believe ext3 would have been invented in the early '90s instead of 2001 :)
