How to Create a ZFS Storage Pool

1. Become root or assume an equivalent role with the appropriate ZFS rights profile.

   For more information about the ZFS rights profiles, see ZFS Rights Profiles.

2. Pick a pool name.

   The pool name is used to identify the storage pool when you are using the zpool or zfs commands. Most systems require only a single pool, so you can pick any name that you prefer, provided it satisfies the naming requirements outlined in ZFS Component Naming Requirements.

3. Create the pool.

   For example, create a mirrored pool that is named tank.

   # zpool create tank mirror c1t0d0 c2t0d0

   If one or more devices contains another file system or is otherwise in use, the command cannot create the pool.

   For more information about creating storage pools, see Creating a ZFS Storage Pool.

   For more information about how device usage is determined, see Detecting In-Use Devices.

4. View the results.

   You can determine if your pool was successfully created by using the zpool list command.
