SYNOPSIS
The mount_mvfs program must never be invoked explicitly.The cleartool mount subcommand invokes an architecture-specific mount command:
DESCRIPTION
This reference page describes the mechanisms that mount VOBs as file systems of type MVFS (the ClearCase multiversion file system).
Automatic VOB Activation at System Startup
At system startup, the architecture-specific ClearCase startup script (see the init_ccase reference page) issues a mount –all command. This activates on the local host all the VOBs that are registered as public in the local host's network region of the ClearCase tags registry. During this procedure, the architecture-specific mount command performs the actual work of mounting the VOB as a file system of type MVFS. (The command is actually a symbolic link to ccase-home-dir/etc/mount_mvfs.)
VOB Activation After System Startup
After system startup, a mount command can be used to activate or reactivate any VOB that is listed in the tags registry.
Automatic VOB Deactivation at System Shutdown
At system shutdown, the architecture-specific ClearCase startup script is invoked with the stop option to execute the ClearCase shutdown procedure. As part of this procedure, a umount –all command deactivates all VOBs currently active on the local host. On all platforms except for AIX 4, umount –all invokes the standard umount(1M) utility directly. On AIX 4, umount –all invokes the architecture-specific mount command /sbin/helpers/mvfsmnthelp with U as its first argument, and /sbin/helpers/mvfsmnthelp then invokes umount(1M).
