NAME

cmount − mount composite file system

SYNOPSIS

cmount [−rvx] [−t time] model dir

DESCRIPTION

cmount attaches the file system model to the file system hierarchy at the directory dir, which must already exist. If dir has any contents prior to the cmount operation, these will remain hidden until the file system is unmounted.  The file system model is the model directory of a composite file system (see cfs(4)). 

Once mounted, the file system model will appear unaltered at the directory dir, except that "transparent" links in the model will be effectively supplanted by the files to which each refers (see cfs(4)).  If the directory dir is exported to the network via NFS, any exportable file systems mounted within the model will be exported along with dir, and may be accessed by network clients as if each were actually a sub-directory within the file system represented by the model.

OPTIONS

−r Read-only — Mount the specified file system read-only, even if the entry in /etc/fstab specifies that it is to be mounted read-write. 

−t Transfer — Initiate the CFS file transfer daemon for the model(see cfsd(8)).  The following value specifies the transfer latency interval in minutes.  The default transfer latency interval is five hours. 

−v Verbose — Display a message indicating the file system being mounted. 

−x Do not permit set-UID execution of programs on this file system. 

SEE ALSO

cfs(4), mount(8), umount(8)

BUGS

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