from LU-1382 The workaround we have consist of removing quota (-b 0 -B 0 -i 0 -I 0) then re-applying them, user by user, but it would be better if quota were automatically propagated during add of new OSTs or, at least, handled by a quotacheck.
After a filesystem extension (ie add of new OSTs), quota are not propagated on newer OSTs.
Running quotacheck, quotaoff or quotaon doesn't change anything to the picture.
