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 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 |
For more information about redundant ZFS pool configurations, see Replication Features of a ZFS Storage Pool.
The new ZFS file system, tank, can use as much of the disk space as needed, and is automatically mounted at /tank.
# mkfile 100m /tank/foo # df -h /tank Filesystem 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.
# 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.
# mkfile 100m /tank/fs/foo # df -h /tank/fs Filesystem 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 Creating a ZFS File System Hierarchy.
