APAR status

  • Closed as program error.

Error description

  • The fuser command may hang when PowerHA tries to kill the
    processes which are handling the filesystems which are to
    be umounted by the cl_deactivate_fs script.
    This is because the fuser command has been changed
    in AIX 6.1 TL4 and is now checking the current working
    directory of the process before killing the process.
    If the current working directory of that process
    is on the NFS filesystem already unexported by HACMP,
    and the NFS filesystem is mounted with the hard option,
    the fuser command will wait indefinitely,
    causing PowerHA to wait indefinitely for the completion
    of the fuser command.
    

Local fix

  • N/A
