Gluster users - Oct 2013 - unremovable directories on 3.3.2

I have a no-replication gluster server which I recently upgraded from
3.2.2.  One array died (in the middle of a migration) and some data was
lost.

Since then one user has been having problems deleting empty directories: 
he is told that "rm: cannot remove `sndaqdata': Directory not
empty" and
the protection changes to d---------.

I assume this is due to inconsistencies in the filesystem stemming from
the crash.

What is the best way to address this?

Thanks for any assistance.
