I guess that is enough votes to justify going ahead and trying an
implementation of the reverse mapping ideas I posted.  But of course
more votes for this is better.  If online incremental fsck is
something people want, then please speak up here and that will very
definitely help make it happen.

On the walk-before-run principle, it would initially just be
filesystem checking, not repair.  But even this would help, by setting
per-group checked flags that offline fsck could use to do a much
quicker repair pass.  And it will let you know when a volume needs to
be taken offline without having to build in planned downtime just in
case, which already eats a bunch of nines.

Daniel
