Synopsis
- VersionVault--Unmount VOBs:
- unmount { vob-tag | -a/ll }
- VersionVault Remote Client--Unmount VOBs from an automatic view:
- umount [ -tag view-tag ] vob-tag ...
Description
The umount command deactivates one or more VOBs on your host by unmounting them as operating-system-level file systems. A VOB is activated on a host by mounting it as a file system of type MVFS (VersionVault 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.
Unmounting all VOBs
umount -all unmounts all public VOBs listed in the VOB registry and all private VOBs owned by the user.
UNIX® and Linux® only--Unmounting the view root directory
Except on Solaris, if you enter umount -all as root on a platform that supports the operating system command umount -a, the viewroot directory (/view) is unmounted. To remount the viewroot directory, you must stop and restart VersionVault.
Restrictions
Identities
- UNIX® and Linux--root can unmount any VOB; other users can unmount any public VOB, and private VOBs they own.
- Windows--Any user can unmount any VOB, public or private.
Locks
No locks apply.
Mastership
(Replicated VOBs only) No mastership restrictions.
Options and arguments
Specifying the VOB
- Default
- None.
- vob-tag
- Unmounts the VOB with this vob-tag, which you must specify exactly as it appears in the vob_tag registry file.
- -a/ll
- Unmounts all public VOBs listed in the VOB registry. On UNIX® and Linux® systems, also unmounts all private VOBs owned by the user.
- -tag view-tag
- Specifies the automatic view for which the specified VOBs are to be unmounted. For automatic views, VOB mounts are per-view: unmounting a VOB from one automatic view does not unmount it from other automatic views on the same host.
Examples
In cleartool single-command mode, cmd-context represents the UNIX system and Linux shells or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.
