[lustre-discuss] Understanding quotas

Could someone please help me understand lustre quotas?

I've created a lustre filesystem called "scratch" using RHEL 7.2 and Lustre 2.8. When I run "lctl get_param qmt.scratch-QMT0000.dt-0x0.*" on the MDT I see for my ID the following:

- id:      20977
  limits:  { hard:            600000000, soft:            500000000, granted:            117440512, time:                    0 }

Can someone tell me what the "granted" field is representing? I know it's not my used quota, that's only 86M and this value is nearer 112G.
