– ext2 doesn’t have a journal
– ext3 is so "default". AND it gets b0rken just as well; on my home fileserver there were errors and fsck.ext3 exited with a SIGSEGV. Yikes. Upgrading to the 1.39-1.40 release from Sarge backports made that go away, luckily, but it’s still icky that it just broke like that and kept on humming along at the same time.
– XFS turned out to be really, really slow with many small files.
– ReiserFS only gave me corruption, headache and a murderer as an author 😉
– ZFS? Quoting Andrew Morton, "I haven’t seen a patch for that yet, but it’s very welcome!"
What to do, what to do…
