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
