Synopsis
- ClearCase®--Unmount VOBs:
- unmount { vob-tag | -a/ll }
- ClearCase® 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 (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.
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 ClearCase®.
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.
