MOUNT_PCFS(8) Maintenance Commands and Procedures MOUNT_PCFS(8)
NAME
mount_pcfs - mount pcfs file systems
SYNOPSIS
mount -F pcfs [
generic_options]
[
-o FSType-specific_options]
special |
mount_point mount -F pcfs [
generic_options]
[
-o FSType-specific_options]
special mount_pointDESCRIPTION
mount attaches an
MS-DOS file system (
pcfs) to the file system hierarchy
at the
mount_point, which is the pathname of a directory. If
mount_point has any contents prior to the
mount operation, these are hidden until the
file system is unmounted.
The
pcfs file system supports direct mounting of files containing the
file system as well as block devices. See
mount(8) and
lofiadm(8).
If
mount is invoked with
special or
mount_point as the only arguments,
mount will search
/etc/vfstab to fill in the missing arguments, including
the
FSType-specific_options; see
mount(8) for more details.
The
special argument can be one of two special device file types:
o A floppy disk, such as
/dev/diskette0 or
/dev/diskette1.
o A DOS logical drive on a hard disk expressed as
device- name:logical-drive, where
device-name specifies the special
block device-file for the whole disk and
logical-drive is
either a drive letter (c through z) or a drive number (1
through 24). Examples are
/dev/dsk/c0t0d0p0:c and
/dev/dsk/c0t0d0p0:1.
The
special device file type must have a formatted
MS-DOS file system
with either a 12-bit, 16-bit, or 32-bit File Allocation Table.
OPTIONS
generic_options See
mount(8) for the list of supported options.
-o Specify
pcfs file system-specific options. The following options are
supported:
clamptime |
noclamptime File timestamps in
pcfs cover a range between January 1st 1980
and December 31st 2127. This is not equal to the range of
time_t on Unix for either 32-bit or 64-bit applications. In particular,
32-bit applications fail with
EOVERFLOW errors on the
stat(2) system call when timestamps beyond the range of 32-bit
time_t are
encountered. In order to prevent such spurious failures,
pcfs by
default clamps timestamps to the common subset of possible
pcfs timestamps and the range available to 32-bit applications in
Unix. The
clamptime mount option therefore is active by default.
If you want access to the full range of possible timestamps on
pcfs, mount the file system with the
noclamptime mount option.
Note that if
noclamptime is used, only 64-bit applications will
have access to timestamps beyond January 19th 2038, 03:14:06 UTC;
32-bit applications will encounter
EOVERFLOW errors.
foldcase |
nofoldcase Force uppercase characters in filenames to lowercase when reading
them from the filesystem. This is for compatibility with the
previous behavior of
pcfs. The default is
nofoldcase.
hidden |
nohidden Allow or disallow listing of files with hidden or system bits
set. Option
hidden is the default. When
nohidden is effect,
hidden and system files are neither visible nor accessible. Note
that PCFS in previous releases of the Solaris operating system
used the
nohidden option as the default.
atime |
noatime Enable or disable write access timestamps on DOS-formatted media.
Default for fixed disks is
atime, while for removable media
noatime is used. The latter default is so that writes to flash-
based media ("memory sticks") can be minimized, to prolong
lifetime.
timezone=timezone Timestamps on DOS-formatted media are recorded in the local time
of the recording system. This can cause confusion when accessing
removable media in which the recording and receiving system use
different time zones. Use this option to force media timestamps
to be interpreted for a specific time zone. The
mount_pcfs command converts the given time zone name into a numerical offset
that is passed to the
pcfs kernel module, using the same rules as
described in
environ(7) for the
TZ environment variable. By
default, the
timezone value is taken from the
TZ environment
variable.

If the directory on which a file system is to be mounted is a symbolic
link, the file system is mounted on the directory to which the symbolic
link refers, rather than on top of the symbolic link itself.
