Creating a ZFS File System
ZFS file systems are created by using the zfs create command. The create subcommand takes a single argument: the name of the file system to create. The file system name is specified as a path name starting from the name of the pool:
pool-name/[filesystem-name/]filesystem-name
The pool name and initial file system names in the path identify the location in the hierarchy where the new file system will be created. All the intermediate file system names must already exist in the pool. The last name in the path identifies the name of the file system to be created. The file system name must satisfy the naming conventions defined in ZFS Component Naming Requirements.
In the following example, a file system named bonwick is created in the tank/home file system.
# zfs create tank/home/bonwick
ZFS automatically mounts the newly created file system if it is created successfully. By default, file systems are mounted as /dataset, using the path provided for the file system name in the create subcommand. In this example, the newly created bonwick file system is at /tank/home/bonwick. For more information about automanaged mount points, see [Managing ZFS Mount Points].
For more information about the zfs create command, see http://docs.sun.com/doc/819-2240.
You can set file system properties when the file system is created.
In the following example, a mount point of /export/zfs is specified and is created for the tank/home file system.
# zfs create -o mountpoint=/export/zfs tank/home
