There must have been some problems for fscks to have needed to fix
problems.

Sounds like some objects have gone missing.  Did you check the lost
+found on the targets that you did fsck to see if anything got relocated
there?

If there are entries there, you will have to try to figure out where
they go back (there was a discussion here in the last week or two about
methods/a tool to do that), or if all else fails, you can run lfsck to
bring the MDT and OSTs back into sync with each other.
