The bug that I recalled from Lustre is unlikely to be the same.  It is
https://bugzilla.lustre.org/show_bug.cgi?id=15932

	"error: N blocks in bitmap, M in gd"

There was a second bug in ext3_mb_use_best_found() hit on > 8TB filesystems:
https://bugzilla.lustre.org/show_bug.cgi?id=16101

	BUG_ON(ac->ac_b_ex.fe_group != e3b->bd_group);


Cheers, Andreas
