SUNWcsu
mount attaches a ufs file
system 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.
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(1M)
.
If special and mount_point are specified without any FSType-specific_options,
the default is rw.
See mount(1M)
for the list of supported generic_options.
- -o
- Specify ufs file system specific options in a comma-separated list with
no intervening spaces. If invalid options are specified, a warning message
is printed and the invalid options are ignored. The following options are
available:
- onerror=action
- where action = panic | lock | umount | repair. This
option specifies the action that UFS
should take to recover from an internal
inconsistency on a file system. These cause a forced system shutdown, a
file system lock to be applied to the file system, the file system to be
forcibly unmounted, or an automatic fsck, respectively. The default is panic.
The repair option downgrades to "panic" if the UFS-aware service daemon
(ufsd) is not installed on the system. ufsd is a component of the unbundled
DiskSuite product.
- toosoon=number[s|m|h|d|w|y]
- This option specifies the minimum
time that must elapse between detection of inconsistencies on a file system.
If an inconsistency is detected within this time period the system is forced
to shut down. This prevents pathologic repairing of a file system which
is damaged repeatedly. The optional unit key letter sets the units to be
seconds, minutes, hours, days, weeks, or years, respectively. The default
value is 1w (1 week).
- f
- Fake an /etc/mnttab entry, but do not actually mount
any file systems. Parameters are not verified.
- m
- Mount the file system without
making an entry in /etc/mnttab.
- quota
- Quotas are turned on for the file
system.
- rw|ro
- Read-write or read-only. Default is rw.
- rq
- Read-write with quotas
turned on. Equivalent to rw, quota.
- nosuid
- By default the file system is
mounted with Setuid execution allowed. Specifying nosuid causes the file
system to be mounted with setuid execution disallowed. nosuid can also be
used to disallow setuid when mounting devices.
- remount
- Used in conjunction
with rw. A file system mounted read-only can be remounted read-write. Fails
if the file system is not currently mounted or if the file system is mounted
rw.
- intr|nointr
- Allow(do not allow) keyboard interrupts to kill a process
that is waiting for an operation on a locked file system. The default is
intr.
- -O
- Overlay mount. Allow the file system to be mounted over an existing
mount point, making the underlying file system inaccessible. If a mount
is attempted on a pre-existing mount point without setting this flag, the
mount will fail, producing the error ‘device busy’.

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.
