Restart. Inactive file system types are not displayed.
- Token
- IBM may request this information
for diagnostic purposes.

all files of this file system type.

This field is only displayed if the file system type is BPXFCSIN.

in the BPXPRMxx parmlib member.

- A PFS in this colony requested thread support.
- The colony has been posted to terminate.
- Thread support has been built for this colony.
- Number of PFSs in this Colony
- Maximum number of PFSs which may start in this colony. This number
matches the number of FILESYSTYPE statements in the BPXPRMxx parmlib
member on which the address space name specified by the ASNAME matches
the preceding address space name.
- Started Colony File Systems
- Type
- Name specified on the TYPE argument of the FILESYSTYPE statement
in the BPXPRMxx parmlib member.
- Token
- IBM may request this information
for diagnostic purposes.
- Extension
- IBM may request this information
for diagnostic purposes.
- Restart (option set by the PFS in the byte addressed by pfsi_restart)
- Prompt the operator.
- Automatic restart.
- No restart.
- Bring down the LFS and the kernel.
- Restart the colony and prompt the operator for the PFS.
- Restart the colony and PFS.
- Bring down the colony but do not restart the PFS.
- PFS status I (as many lines as apply are displayed).
- PFS initialization in progress.
- PFS has been started.
- PFS initialization failed.
- PFS is dead.
- The colony has been posted to terminate.
- Colony PFS initialization has completed.
- PFS status II (as many lines as apply are displayed).
- The PFS will run alone in this colony.
- The PFS will use colony thread support.
- The PFS is written in C.
- The PFS supports DATOFF moves for page read operations.
- Mounted File System Specific Information
- Mounted File System Name
- Name specified on the FILESYSTEM argument of the mount() system
call, TSO/E MOUNT command or the MOUNT statement in the BPXPRMxx parmlib
member.
- Mount Point
- PathName (at time of MOUNT)
- Name specified on the PATH argument of the mount() system
call, or on the MOUNTPOINT parameter of either the TSO/E MOUNT command
or the MOUNT statement in the BPXPRMxx parmlib member. If the pathname
is greater than 64 characters, it is preceded by a plus sign to indicate
truncation.
- File Serial Number
- The file ID of the mount point. This value will match st_ino returned
from stat() for the mount point.
- Device Number
- The unique ID for this mounted file system. For files in this
file system, this value will match the st_dev returned
from stat().
- DD Name
- The ddname corresponding to the MVS™ data
set name that contains the mounted file system. This name is either
specified on the DDNAME parameter of the MOUNT statement in the BPXPRMxx
parmlib member or is returned by the system when the mount for the
file system is complete.
- Token
- IBM may request this information
for diagnostic purposes.
- Number of Active Files for this Mounted File System
- Number of files that are either open or recently referenced.
- Number of Files Pending Inactive
- Number of pending inactive files that are no longer being referenced
and whose meta data is about to be removed from the in-storage cache.
- PathConf Data
- The following 4 fields apply only if the file system type is not
an IBM reserved type, which
have names starting with the characters BPX.
- Link_max
- Maximum value of a file's link count.
- Name_max
- Maximum number of bytes in a filename. The number is not a string
length; it excludes the terminating null.
- Posix_No_trunc?
- If the value is Y, pathname components longer than NAME_MAX generate
an error. If N, only the first NAME_MAX bytes are used. Valid values
are Y for yes and N for no.
- Posix_Chown_restricted?
- If the value is Y, the use of the chown() function
is restricted for files in this mounted file system. A value of N
indicates the use of chown() is not restricted. Valid
values are Y for yes and N for no. The POSIX standard fully describes
_POSIX_CHOWN_RESTRICTED.
- File System was Mounted Read-Only
- Displayed when applicable. If the file system was mounted Read-Write,
no message is displayed.
- type Unmount is in Progress
- If an unmount is in progress, this line is displayed and type indicates
the type of unmount. The possible values for type are:
- Drain
- Force
- Immediate
- Normal
- Reset
- This File System has been Quiesced
- Displayed when the file system has been quiesced.
- This is the System Root File System
- Displayed when applicable.
- Root File Serial Number
- If this is not the system root file system, this line displays
the file serial number for the root of the mounted file system.
- Max_input
- Minimum number of bytes for which space will be available in a
workstation input queue; therefore, the maximum number of bytes a
portable application may require to be typed as input before reading
them. This field is only displayed if the file system type is BPXFCSIN.
- _Posix_VDisable
- This character value can be used to disable workstation special
characters. This field is only displayed if the file system type
is BPXFCSIN.
