Oracle Solaris ZFS Administration Guide

ZFS Property Improvements

ZFS xattr Property

Solaris 10 8/07 Release: You can use the xattr property to disable or enable extended attributes for a specific ZFS file system. The default value is on. For a description of ZFS properties, see Introducing ZFS Properties.

ZFS canmount Property

Solaris 10 8/07 Release: The new canmount property enables you to specify whether a dataset can be mounted by using the zfs mount command. For more information, see canmount Property.

ZFS User Properties

Solaris 10 8/07 Release: In addition to the standard native properties that can be used to either export internal statistics or control ZFS file system behavior, ZFS provides user properties. User properties have no effect on ZFS behavior, but you can use them to annotate datasets with information that is meaningful in your environment.

For more information, see ZFS User Properties.

Setting Properties When Creating ZFS File Systems

Solaris 10 8/07 Release: In this Solaris release, you can set properties when you create a file system, not just after the file system is created.

The following examples illustrate equivalent syntax:

# zfs create tank/home
# zfs set mountpoint=/export/zfs tank/home
# zfs set sharenfs=on tank/home
# zfs set compression=on tank/home

# zfs create -o mountpoint=/export/zfs -o sharenfs=on -o compression=on tank/home
