Creating Oracle Solaris File Systems

This section provides an overview of creating Oracle Solaris file systems.

Creating ZFS File Systems

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.

A ZFS file system is created by using the zfs create command. A ZFS file system is automatically mounted when it is created. For more information, see How to Create an ZFS File System.

For more information about creating ZFS storage pools and file systems, see Oracle Solaris 11.1 Administration: ZFS File Systems.

Creating a Temporary File System

A temporary file system (TMPFS) uses local memory for file system reads and writes. TMPFS file systems can improve system performance by saving the cost of reading and writing temporary files to a local disk or across the network. Files in TMPFS file systems do not survive across reboots or unmounts.

If you create multiple TMPFS file systems, be aware that they all use the same system resources. Files created under one TMPFS file system use up space available for any other TMPFS file system, unless you limit TMPFS sizes by using the -o size option of the mount command.

For more information about creating and mounting a TMPFS file system, see How to Create and Mount a TMPFS File System.

For general information, see the tmpfs(7FS).

Creating a LOFS File System

An LOFS file system is a virtual file system that provides an alternate path to an existing file system. When other file systems are mounted onto an LOFS file system, the original file system does not change.

For more information about creating and mounting a LOFS file system, see How to Create and Mount an LOFS File System.

For general information, see the lofs(7FS).


Note - Be careful when creating LOFS file systems. Because LOFS file systems are virtual file systems, the potential for confusing both users and applications is enormous.
