SUJ speeds up the check a lot, seconds as opposed to minutes. If

But fsck needs to be run manually- I have users that can't do that,
and the filesystem corrupts. Ergo gjournal; it boots up and fixes on
the fly. So SU+J needs a manual fsck before booting proper or can it
just boot and be done?
It's not very different; gjournal and SU both attempt to leave the
filesystem in an coherent state, but both still need a preen to
recover lost space. In either case the preen can fail requiring a full
fsck.
Journalled SU make SU behave more like gjournal in that you can do a
fast foreground check which avoids the lengthy background fsck and
avoids deferring the handling of unexpected inconsistencies to the next
boot.
Yes, but I don't do a fsck to recover gjournal- it has a miniscule blurp
for a nanosecond and prints a message at boot and thats it. Is it the
same with su+j? If it does then I'll drop gjournal (and the performance
hit) and I'll use su+j when I jump to 9.0.
I've never done fsck on a gjournal (yet).
