Opensolaris.org has a number of public mailing lists called 'discussions', covering a variety of subjects. Use this link to sign up to the ZFS discussion.
This is a demo of the basics of using ZFS, it comes from the OpenSolaris ZFS Community and requires Flash. The presentation is by no means complete, so make sure to have a look at the ZFS documentation (Open Solaris) for a complete reference.
The ZFS Boot project, the team is working to provide the ability to boot the Solaris Operating System from a ZFS root file system as well as install the Solaris Operating System to a ZFS file system.
From www.oracle.com:
This White Paper describes the detailed design goals of ZFS and shows examples of using ZFS. You should note that the document was created during ZFS development and while the overall information is correct much of the command syntax has changed.
ZFS Snapshot Auditing. A perl script to compare a live ZFS filesystem against a ZFS snapshot of the same filesystem in order to get an idea of the files that differ between them.

ZFS The Next Word..., a presentation by Bonwick and Moore the creators of ZFS. These features have been integrated into ZFS, some in Oracle Solaris 10 and Oracle Solaris 11.
zpool history command, starting with the Solaris 10 8/07 release, ZFS automatically logs successful zfs and zpool commands that modify pool state information. This feature enables you or Sun support personnel to identify the exact set of ZFS commands that was executed to troubleshoot an error scenario.
Starting with the Solaris 10 8/07 release, you can set properties when you create a file system, in addition to setting properties after the file system is created.
This example creates a file system and changes three properties:
chaos:/> zfs create bpool/home
chaos:/> zfs set mountpoint=/export/zfs bpool/home
chaos:/> zfs set sharenfs=on bpool/home
chaos:/> zfs set compression=on bpool/home
This example creates the files system and sets the properties is a single command:
chaos:/> zfs create -o mountpoint=/export/zfs -o sharenfs=on -o compression=on bpool/home
chaos:/> zfs list -o mountpoint,sharenfs,compression bpool/home
MOUNTPOINT SHARENFS COMPRESS
/export/zfs on on
Property Changes...
shareiscsi property, starting with the Solaris 10 8/07 release, you can create a ZFS volume as a Solaris iSCSI target device by setting the shareiscsi property on the ZFS volume. This method is a convenient way to quickly set up a Solaris iSCSI target.
ZFS canmount property, starting with the Solaris 10 8/07 release, you use the canmount property to specify whether a dataset can be mounted by using the zfs mount command.
The first example shows a existing directory in /export/home on this system, the canmount property is used to "add" the ZFS home directory file systems to this existing UFS file system.

The next example uses the canmount property to configure to sets of directories under the same mountpoint that can have different ZFS properties set.
chaos:/> zfs create -o mountpoint=/development -o canmount=off bpool/development
chaos:/> zfs create -o mountpoint=/development -o canmount=off bpool/admin
chaos:/> zfs create bpool/development/mernest
chaos:/> zfs create bpool/admin/fsayers
chaos:/> ls -F /development

chaos:/> zfs set compression=on bpool/development
chaos:/> zfs get compression bpool/development/mernest

ZFS user properties, starting with the Solaris 10 8/07 release, ZFS supports user properties, in addition to the standard native properties that can either export internal statistics or control ZFS file system behavior. User properties have no effect on ZFS behavior, but you can use them to annotate data sets with information that is meaningful in your environment. User property names must contain a colon (":") character, to distinguish them from native properties.
