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.
