Description of problem:
In both the clusterfs.sh and fs.sh, if you need to force unmount a
filesystem, calling killMountProccesses(), you will always fail.  This
is because the fuser (will have to check lsof next, I suppose) is not
functioning the way it used to.  Don't know why (device-mapper?).

[root@link-12 gfs1]# mount | grep gfs
/dev/mapper/VG1-LV1 on /mnt/gfs1 type gfs (rw,noatime,nodiratime)
[root@link-12 gfs1]# fuser -vm /mnt/gfs1

                     USER        PID ACCESS COMMAND
/mnt/gfs1            root      29425 ..c..  bash
[root@link-12 gfs1]# fuser -vm /dev/mapper/VG1-LV1
[root@link-12 gfs1]#

Version-Release number of selected component (if applicable):
rgmanager-1.9.24-0

How reproducible:


Steps to Reproduce:
1. Set force_unmount=1 if using clusterfs
2. Start clusterfs service
3. Put a pid on the fs
4. Try to relocate it
  
Actual results:
Fails to properly kill pids on fs.

Expected results:
Pids killed, relocate successful.
