The reason for --force is:
Error: missing required option(s): 'ipaddr, login, plug' for resource type:
stonith:fence_vbox (use --force to override)
I have selinux disabled on both nodes:
[root at nfsnode1 ~]# cat /etc/sysconfig/selinux
SELINUX=disabled
pcs stonith update vbox-fencing verbose=true
Error: resource option(s): 'verbose', are not recognized for resource type:
'stonith::fence_vbox' (use --force to override)
It worked with --force:
