The quota accounting is controlled by the backing filesystem of the OSTs and MDTs.
For ldiskfs/ext4 you could run e2fsck to re-count all of the inode and block usage. For ZFS you would have to ask on the ZFS list to see if there is some way to re-count the quota usage. The "inode" quota is accounted from the MDTs, while the "block" quota is accounted from the OSTs. You might be able to see with "lfs quota -v -g group" to see if there is one particular MDT that is returning too many inodes. Possibly if you have directories that are striped across many MDTs it would inflate the used inode count. For example, if every one of the 426k directories reported by RBH was striped across 4 MDTs then you would see the inode count add up to 3.6M. If that was the case, then I would really, really advise against striping every directory in the filesystem. That will cause problems far worse than just inflating the inode quota accounting.
