| # zfs set quota=500m space/slice1 |
Limit the /cool slice to 500MB |
| # zfs set userquota@frantisek=300M space/slice1 |
Show user quota for frantisek |
| # zfs get userquota@frantisek space/slice1 |
Show user quota for frantisek on that FS |
| # zfs set groupquota@staff=1G space/slice1 |
Set group quota on the slice |
| # zfs get groupquota@staff space/slice1 |
Show group quota on the slice |
| # zfs userspace space/slice1 |

| # zfs snapshot space/slice1@tuesday |
Create a snapshot of a filesystem and call that snapshot tuesday |
| # zfs snapshot -r space/slice1@fiveaclock |
Create a snapshot of a filesystem with all recursive filesystems |
| # zfs list -t snapshots |
List available snapshots |
| # ls /space/space/slice1/.zfs/snapshot/fiveaclock/ |

Revert back to the earlier snapshot over existing newer snapshots |
# zfs snapshot -r space/slice1@fiveaclock
# zfs clone space/slice1@fiveaclock space/fiveaclockclone |
Create a clone (a new fs with a status of one moment of the fs) |
| #zfs destroy space/fiveaclockclone |
Destroy a clone - CLONE IS NOT A FULLFEATURED COPY OF THE FS |
# zfs snapshot -r space/slice1@sixaclock
# zfs send space/slice1@sixaclock |zfs rcv space/slice3 |
ZFS SEND creates a full featured copy of the fs (first snap and then clone) |
