== VDEV Properties (Allan Jude) == | == VDEV Properties (Allan Jude) == | ||
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. | |||
This talk will discuss the finalized version of the concept and include recent work to implement queuing for device removals via VDEV properties. | |||
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. |
