Oh, well.. Journalling sucks.
Go back to ext2? ;)
I was actually _really_ hoping that somebody would come along and tell
everybody that this whole journal-logging is stupid, and that it's just
better to not ever re-write blocks on disk, but instead write to new
blocks with version numbers (and not re-use old blocks until new versions
are stable on disk).
Ah, "copy on write"! ZFS (Sun) and WAFL (NetApp) does this. Don't know
about WAFL, but ZFS does logging too.
