HP-UX Reference (11i v2 07/12) - 1M System Administration Commands A-M (vol 3)

m
mount_memfs(1M) mount_memfs(1M)
suid Allow set-user-ID execution (default).
nosuid Do not allow set-user-ID execution.
-p Report the list of mounted file systems in the
/etc/fstab format.
-Q Prevent the display of error messages resulting from an attempt to mount already
mounted file systems.
-v Report the regular output with file system type and flags; however, directory and special
fields are reversed. The special field for
memfs always contains the text memfs.
-V Echo the completed command line, but performs no other action. The command line is
generated by incorporating the user-specified options and other information derived from
/etc/fstab . This option allows the user to verify the command line.
Options (umount)
umount recognizes the following options:
-a Attempt to unmount all file systems described in
/etc/mnttab . All optional fields in
/etc/mnttab must be included and supported. If -F memfs is specified, all MemFS
file systems in /etc/mnttab are unmounted. File systems are not necessarily
unmounted in the order listed in /etc/mnttab .
-F memfs Specify the MemFS file system type (see fstyp(1M)).
-v Verbose mode. Write a message to standard output indicating which file system is being
unmounted.
-V Echo the completed command line, but performs no other action. The command line is
generated by incorporating the user-specified options and other information derived from
/etc/fstab . This option allows the user to verify the command line.
Notes
Quotas are not available for MemFS filesystems.
MemFS filesystems are largefiles-enabled.
MemFS filesystems do not support forced unmount.
MemFS filesystems cannot be mounted read only.
DIAGNOSTICS
umount complains if the directory is not mounted or if it is busy. The file system is busy if it contains an
open file or some logged-in user’s working directory.
EXAMPLES
Mount a MemFS of size 100 MB on /mnt:
mount -F memfs -o size=100MB /mnt
Unmount a local MemFS disk:
umount /mnt
