ZFS: Create a Mirrored Storage Pool

Last Updated on

Anyone who has used DiskSuite to mirror drives in Solaris knows that, while not difficult, the multiple steps involved are fertile ground for (potentially devastating) heartache. This is not the case with ZFS. Creating a mirrored pool with ZFS makes DiskSuite look like rocket surgery.

To create a mirrored pool ‘stuff’ out of the disks c0t0d0 and c0t1d0, use the following command:

zpool create stuff mirror c0t0d0 c0t1d0

It is done. Who needs GUIs? The filesystem mounted as /stuff is mirrored and ready for use. A mirrored ZFS filesystem can be used exactly like other ZFS filesystems.
