Sharing ZFS File System Enhancements

Solaris Express Community Release, build 53: In this Solaris release, the process of sharing file systems has been improved. Although modifying system configuration files, such as /etc/dfs/dfstab, is unnecessary for sharing ZFS file systems, you can use the sharemgr command to manage ZFS share properties. The sharemgr command enables you to set and manage share properties on share groups. ZFS shares are automatically designated in the zfs share group.

As in previous releases, you can set the ZFS sharenfs property on a ZFS file system to share a ZFS file system. For example:

# zfs set sharenfs=on tank/home

Or, you can use the new sharemgr add-share subcommand to share a ZFS file system in the zfs share group. For example:

# sharemgr add-share -s tank/data zfs
# sharemgr show -vp zfs
zfs nfs=()
    zfs/tank/data
          /tank/data
          /tank/data/1
          /tank/data/2
          /tank/data/3

Then, you can use the sharemgr command to manage ZFS shares. The following example shows how to use sharemgr to set the nosuid property on the shared ZFS file systems. You must preface ZFS share paths with a /zfs designation.

# sharemgr set -P nfs -p nosuid=true zfs/tank/data
# sharemgr show -vp zfs
zfs nfs=()
    zfs/tank/data nfs=(nosuid="true")
          /tank/data
          /tank/data/1
          /tank/data/2
          /tank/data/3
