We worked on supporting this using the ASIZE of the blkptr and maintaining logical-size (aka. pre-compression) for each object. Also, we added an additional field in the user/group quota entries to maintain the logical consumption. Application of the quota is controlled by a dataset level property. | We worked on supporting this using the ASIZE of the blkptr and maintaining logical-size (aka. pre-compression) for each object.

The ZFS properties interface is a powerful and expressive administrative interface, already used for datasets, snapshots, and pools. This work extends that paradigm to VDEVs as well. | The ZFS properties interface is a powerful and expressive administrative interface, already used for datasets, snapshots, and pools.

Other uses include exposing more statistics about vdevs, and in the future, possibly moving some tunables to be per-vdev (vdev queues, aggregation, etc). | Other uses include exposing more statistics about vdevs, and in the future, possibly moving some tunables to be per-vdev (vdev queues, aggregation, etc). | ||
The talk will also cover the new functionality of the “allocatable” property, for disabling allocations/writes on certain vdevs. | The talk will also cover the new functionality of the “allocatable” property, for disabling allocations/writes on certain vdevs. | ||
