This is what I see when I test it on our cluster here, this is a demo filesystem so very small hence the quotacheck happens very quickly, on a real fs you should see more processes.
$ pdsh -a ps auwx | grep quota
sabina-client0: root 6621 0.0 0.0 4280 464 pts/1 S+ 13:36 0:00 lfs quotacheck /lustre/sab/client
sabina-oss1: root 30278 0.0 0.0 0 0 ? D 13:36 0:00 [quotacheck]
sabina-mds1: root 12310 0.0 0.0 61160 776 pts/0 S+ 13:36 0:00 grep quota
This is on a 1.8 filesystem, I believe it used to work differently on 1.6.
