The big question here is if you can grow the filesystem to fix it.

Before i found the workaround with the agcount i tested to grow the fs, 
but it didn't work.

So: A correctly(tm) fixed package i think it must include a xfs_grows 
that can fix a damaged(tm) fs, otherwise people who use such a 
filesystem (and can't backup/restore) are stuck with missing a large 
chunk of space.
