ZFS Pool Version 9

This page describes the features that are available with the ZFS on-disk format, version 9. This version includes support for the following features:

• In addition to the existing ZFS quota and reservation features, this release includes dataset quotas and reservations that do not include descendent datasets, such as snapshots and clones, in the space consumption. ("zfs set refquota" and "zfs set refreservation".)

• A reservation is automatically set when a non-sparse ZFS volume is created that matches the size of the volume. This release provides an immediate reservation feature so that you set a reservation on a non-sparse volume with enough space to take snapshots and modify the contents of the volume.

• CIFS server support

These features are available in Solaris Express Community Edition, build 77.

The related bugs for version 9 changes are:

• 6431277 want filesystem-only quotas

• 6483677 need immediate reservation

• 6617183 CIFS Service – PSARC 2006/715
