Create ZFS Pool for Cloning Zones

If you plan to use a Solaris ZFS^TM snapshot as your zone template, you need to create a ZFS pool from a ZFS file or a ZFS device. This pool holds the snapshot for cloning each zone. You use the /zone device for your ZFS pool.

Before You Begin

You have set aside disk space during Solaris installation for a ZFS file system. For details, see Planning for Zones in Trusted Extensions.

1. Unmount the /zone partition.

   During installation, you created a /zone partition with sufficient disk space of about 2000 MBytes.

   # umount /zone

2. Remove the /zone mount point.

   # rmdir /zone

3. Comment out the /zone entry in the vfstab file.

   1. Prevent the /zone entry from being read.

      Open the vfstab file in an editor. Prefix the /zone entry with a comment sign.

      #/dev/dsk/cntndnsn /dev/dsk/cntndnsn /zone ufs 2 yes -

   2. Copy the disk slice, cntndnsn, to the clipboard.

   3. Save the file, and close the editor.

4. Use the disk slice to re-create /zone as a ZFS pool.

   # zpool create -f zone cntndnsn

   For example, if your /zone entry used disk slice c0t0d0s5, then the command would be the following:

   # zpool create -f zone c0t0d0s5

5. Verify that the ZFS pool is healthy.

   Use one of the following commands:

   # zpool status -x zone pool 'zone' is healthy

   # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT /zone 5.84G 80K 5.84G 7% ONLINE -

   In this example, the initial setup team reserved a 6000 MByte partition for zones. For more information, see the zpool(1M) man page.
