mount(8ufs)mount(8ufs)Namemount - mount the local ULTRIX File System (UFS)
/etc/mount [ -t ufs -r ] [ options ] device directory
The command announces to the system that a file system is present on
the device device. The specified device must be a local device. The
file directory must exist and it must be a directory. It becomes the
name of the newly mounted file system.
To further protect from system crashes, only file systems that have
been cleanly checked by are mounted. In emergency situations, the
superuser can override this requirement by using the option as shown
General users can mount file systems with certain restrictions in addi‐
tion to those listed in The file system must have the clean byte set.
To ensure the clean byte is set, run the command on the file system
first. You can also try the mount and if it fails, then run and then
try the mount again.
Note that the user must have execute permissions on the device.
A successful ufs-mount may generate the following warning message:
"Warning, device has exceeded xxx threshold, fsck(8) is advised"
where xxx is which metric was exceeded to cause the clean byte timeout
factor to reach zero. See for an explanation of the timeout algorithm.
Physically write-protected disks and magnetic tape file systems must be
mounted read only or an error will occur at mount time.
See the reference page for a description of the -t option.
-o options Specifies options as a sequence of comma-separated words
from the list below.
force The superuser can force the mounting of
unclean file systems. You should use the
flag only in single-user mode when repairing
or recovering damaged file systems.
nodev Block and character special devices cannot be
accessed from this file system. If you are
concerned with nfs security, all ufs file
systems that will be exported via nfs should
be ufs mounted with the option.
noexec Binaries cannot be executed from this file
nosuid The and programs may not be executed from
this file system. If you are concerned with
nfs security, all ufs file systems that will
be exported via nfs with the option specified
in the file should be ufs mounted with the
pgthresh=## Set the paging threshold for this file system
in kilobytes. The default is 64 kilobytes.
sync All writes are immediately written to disk
(synchronously) as well as to the buffer
cache. For the option to be meaningful, the
file system must be mounted with write per‐
-r Mounts the device on directory read only.
The command should only be invoked by the command. Users (and supe‐
rusers) should not invoke the command.
The command calls to do its work and is the preferred interface. A
sample command is:
# mount-t ufs -o nodev,nosuid,noexec,pgthresh=100 /dev/ra0g /usr
