Hi,

Yeah, the gfs_fsck has more smarts as far as recovering its oddly-spaced
rgrps.  I've talked about extracting that code from gfs_fsck and adding
it to fsck.gfs2, but so far we've been too busy.  I haven't even opened
a bugzilla on it yet.  If you open a bugzilla, I'll work on it, but that
will take a fair amount of testing before it will be ready.

The other issue is that it sounds like there might be a bug in
gfs2_grow when dealing with these oddly-spaced rgrps as well.
That needs to be investigated more fully.  I'd also like a
bugzilla bug record for that work as well.
