A ZFS file system is not directly tied to a specific disk partition. A ZFS file system is contained with a ZFS storage pool that can contain many devices. Either whole disks or disk slices can be added to a ZFS storage pool. Within a pool, you will probably want to create additional file systems. File systems provide points of administration that allow you to manage different sets of data within the same pool.

For more information about creating ZFS storage pools and file systems, see Oracle Solaris ZFS Administration Guide.

How to Create an Oracle Solaris ZFS File System

You must be superuser or assume an equivalent role.
Create a ZFS storage pool.
The following example illustrates how to create a simple mirrored storage pool named tank and a ZFS file system named tank in one command. Assume that the whole disks /dev/dsk/c1t0d0 and /dev/dsk/c2t0d0 are available for use.
```
# zpool create tank mirror c1t0d0 c2t0d0
```
Create a ZFS file system.
```
# zfs create tank/fs
```
The new ZFS file system, tank/fs, can use as much of the disk space as needed, and is automatically mounted at /tank/fs.

Confirm that the file system is created.

# zfs list -r tank
NAME      USED  AVAIL  REFER  MOUNTPOINT
tank      117K   268G    21K  /tank
tank/fs    21K   268G    21K  /tank/fs
