umount

Deactivates a VOB

APPLICABILITY

ClearCase (cleartool subcommand), Attache (command)

SYNOPSIS

umount { vob-tag | -a·ll }

DESCRIPTION

The umount command deactivates one or more VOBs on your host by unmounting them as Windows-level file systems. A VOB is activated on a host by mounting it as a file system of type MVFS (ClearCase multiversion file system type). The VOB-tag by which an individual VOB is referenced is the same as the full pathname to its mount point.

Note that umount has no impact on a VOB's entries in the vob_object and vob_tag registry files.

Unmounting of Public and Private VOBs

Any user can unmount any VOB, public or private.

See the mkvob reference page for a discussion of public and private VOBs.

Unmounting All VOBs

umount -all unmounts all public VOBs listed in the VOB registry and all private VOBs owned by the user.
