NAME

mount_ufs − mount ufs file systems

SYNOPSIS

mount −F ufs [ generic_options ] [ −o FSType-specific_options ] [ −O ]

special| mount_point
mount −F ufs [ generic_options ] [ −o FSType-specific_options ] [ −O ]

special mount_point

DESCRIPTION

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. 

OPTIONS

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:

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. 

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”. 

FILES

/etc/mnttab table of mounted file systems

/etc/vfstab list of default parameters for each file system

NOTES

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.
