The quota concept in ZFS ist just different... |

|
| 17 |
While Linux just uses the Melbourne Quota code that has been written for *BSD, |
| 18 |
zfs uses a new concept that fits the constraints of a COW filesystem with |
| 19 |
writable snapshots. |

ZFS may on the other side may allow to write much more than in the limitation |
| 23 |
data as the quota is checked only when a sync() happens (which is aprox. every |
| 24 |
3 seconds). |
