|
Read-only property that identifies the amount of disk space that is used by a dataset itself, which would be freed if the dataset was destroyed, after first destroying any snapshots and removing any refreservation reservations. The property abbreviation is usedds. |
| usedbysnapshots |
usedbysnapshots |
gauge |
|
|
Read-only property that identifies the amount of disk space that is consumed by snapshots of a dataset. In particular, it is the amount of disk space that would be freed if all of this dataset's snapshots were destroyed. Note that this value is not simply the sum of the snapshots' used properties, because space can be shared by multiple snapshots. |

gauge |
|
|
Read-only property that identifies the amount of disk space that is used by a refreservation set on a dataset, which would be freed if the refreservation was removed. |

usedbychildren |
gauge |
|
|
Read-only property that identifies the amount of disk space that is used by children of this dataset, which would be freed if all the dataset's children were destroyed. The property abbreviation is usedchild. |
| available |
available |
gauge |
|
|
Read-only property that identifies the amount of disk space available to a file system and all its children, assuming no other activity in the pool. Because disk space is shared within a pool, available space can be limited by various factors including physical pool size, quotas, reservations, and other datasets within the pool. |
| quota |
quota |
gauge |
|
|
Limits the amount of disk space a file system and its descendents can consume. This property enforces a hard limit on the amount of disk space used, including all space consumed by descendents, such as file systems and snapshots. Setting a quota on a descendent of a file system that already has a quota does not override the ancestor's quota, but rather imposes an additional limit. Quotas cannot be set on volumes, as the volsize property acts as an implicit quota. |
| refquota |
refquota |
gauge |
|
|
Sets the amount of disk space that a dataset can consume. This property enforces a hard limit on the amount of space used. This hard limit does not include disk space used by descendents, such as snapshots and clones. |
| referenced |
referenced |
gauge |
|
|
Read-only property that identifies the amount of data accessible by a dataset, which might or might not be shared with other datasets in the pool. When a snapshot or clone is created, it initially references the same amount of disk space as the file system or snapshot it was created from, because its contents are identical. |
| reservation |
reservation |
gauge |
|
|
Sets the minimum amount of disk space guaranteed to a file system and its descendents. When the amount of disk space used is below this value, the file system is treated as if it were using the amount of space specified by its reservation. Reservations are accounted for in the parent file system's disk space used, and count against the parent file system's quotas and reservations. |
| refreservation |
refreservation |
gauge |
|
|
Sets the minimum amount of disk space that is guaranteed to a dataset, not including descendents, such as snapshots and clones. When the amount of disk space used is below this value, the dataset is treated as if it were taking up the amount of space specified by refreservation. The refreservation reservation is accounted for in the parent dataset's disk space used, and counts against the parent dataset's quotas and reservations. If refreservation is set, a snapshot is only allowed if enough free pool space is available outside of this reservation to accommodate the current number of referenced bytes in the dataset. |
