Looks like you had something write crap over various parts of
the filesystem. Both AG 2 and ag 24 have header problems, and
then there's a bunch of freespace and allocated inode problems
because the indexes were lost due ot the header corruption.
Who knows how much else is broken - it depends on how much
bad data got written into the filesystem. best you can do is
to run xfs_repair and sift through the debris in lost+found
and try to work out what the lost data is...
As I always ask - how did the filesytem get into this state?
Cheers,
Dave.
