ZFS administration has been designed with simplicity in mind. Among the goals of the ZFS design is to reduce the number of commands needed to create a usable file system. When you create a new pool, a new ZFS file system is created and mounted automatically.
The following example illustrates how to create a storage pool named
tank and a ZFS file system name
tank in one
command. Assume that the whole disk
available for use.
zpool create tank c1t0d0
The new ZFS file system,
tank, can use as much
of the disk space on
c1t0d0 as needed, and is automatically
mkfile 100m /tank/foo#
df -h /tankFilesystem size used avail capacity Mounted on tank 80G 100M 80G 1% /tank
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.
The following example illustrates how to create a file system named
fs in the storage pool
tank. Assume that the
/dev/dsk/c1t0d0 is available for use.
zpool create tank c1t0d0#
zfs create tank/fs
mkfile 100m /tank/fs/foo#
df -h /tank/fsFilesystem size used avail capacity Mounted on tank/fs 80G 100M 80G 1% /tank/fs
In most cases, you will probably want to create and organize a hierarchy of file systems that matches your organizational needs. For more information about creating a hierarchy of ZFS file systems, see.
