PH33465: AUTOMOUNTING A VOB MAY NOT OCCUR WHEN USING VIEW-EXTENDED ACCESSIF THE VOB WAS MANUALLY UNMOUNTED USING CLEARTOOL UMOUNT

APAR status

• Closed as program error.

Error description

• Using the IBM Rational ClearCase vob automount feature may not
  work correctly if automounted VOBs are manually unmounted using
  cleartool umount.
  
  If VOBs are manually unmounted, the VOBs will not remount when
  using view-extended access (example: ls
  /view/myview/vobs/automountvob/dir1). Re-attempting this access
  in a freshly "set" view (cleartool setview myview; ls
  /vobs/automountvob/dir1) may work to mount the VOB...
  

Local fix

• Do not manually umount any VOB that was automounted using the OS
  automounter.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Users of the VOB automounting feature of ClearCase on Linux  *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * The problem may be seen on Linux systems which have the VOB  *
  * automounting feature enabled.  After a VOB has been          *
  * successfully automounted at least one time, the same VOB may *
  * fail to mount again on a subsequent access through a         *
  * view-extended pathname.   The problem is typically seen when *
  * the automounted VOB is manually unmounted by a cleartool     *
  * unmount command, rather than being unmounted by the          *
  * automounter after a period of inactivity.                    *
  ****************************************************************
  * RECOMMENDATION:                                              *

Problem conclusion

• This problem is fixed in ClearCase versions 9.0.1.12, 9.0.2.4,
  and 9.1.0.1.
