FS—file system

The FS (file system) line command can be entered against any directory entry except a FIFO or character special file. This line command causes the z/OS® UNIX File System Attributes panel to be displayed.

This panel displays the attributes of the file system for the file in these fields:

File system name

The name of the data set for the file system.

Mount point

The name of the directory that is the mount point for this file system.

Status

One of these values describing the current state of the file system:

Available: The file system is mounted and available for use.
Not Active: The file system is not available for use.
Reset in progress: A reset unmount request is currently being processed.
Unmount drain in progress: The file system will be unmounted when it is no longer in use.
Unmount force in progress: The file system is being unconditionally unmounted.
Unmount immediate in progress: The file system is being unmounted, even though it may be in use.
Unmount in progress: The file system is being unmounted if it is not currently in use.
Pending unmount reset or force: An immediate unmount request failed.
Quiesced by (process ID): The file system is quiesced, usually for backup.
Mount in progress: The file system is being mounted.
Recycling: The physical file system is in a recycle but a mount has not yet been done for this file system.
Recycling, Asynch Mounting: The physical file system is in a recycle and the file system is in an asynchronous mount.
Recycling, Not Active: The physical file system is in a recycle and the file system failed to successfully mount.
Unowned: The file system has become unowned.
In Recovery: Recovery processing is in progress.
Super Quiesced: The file system is in a super quiesced state.

File system type

The type of physical file system that manages this mounted file system.

Mount mode

Shows whether the file system is mounted read/write (R/W) or read-only(R/O).

Device number

The device number that uniquely identifies the mounted file system. This is a hexadecimal value.

Type number

A number set by the physical file system to indicate the type of this file system. The HFS file system sets this value to 1.

DD name

The MVS™ data definition name used by the physical file system to access the mounted file system.

Ignore SETUID

This value indicates whether the SETUID and SETGID mode bits on any executable in this file system be ignored when the program is run.

Bypass Security

This value indicates whether security checks are not enforced for files in this file system.

Automove

This value indicates whether the system can automatically move the file system to another system and remain local and unowned, or be unmounted.

Owning system

The name of the system that owns this file system.

CCSID

The coded character set identifier to be implicitly set for untagged files in the file system.

Text Convert

This value indicates whether untagged files are implicitly marked as containing pure text data that can be converted.

Seclabel

This security label assigned to a file system that is mounted read-only. This security label applies to all objects within the file system that do not have security labels assigned.

Block size

The length, in bytes, of a data block for the physical file system.

Total blocks

The total number of 4096-byte blocks in this file system.

Available blocks

The number of 4096-byte blocks in this file system that are available for use.

Blocks in use

The number of 4096-byte blocks in this file system that are currently in use.

Data blocks read

The block I/O count for user data reads. This value is only available if SMF type 92 records are active.

Data blocks written

The block I/O count for user data writes. This value is only available if SMF type 92 records are active.

Directory blocks r/w

The block I/O count for directory I/Os. This value is only available if SMF type 92 records are active.

Mount parameters

The parameters specified with the mount command for this file system.
