I wrote about fence_ack_manual, not about fence_manual. fence_ack_manual 
isn't a fence agent, it's confirmation tool like stonith_admin -C.

Ok. I'll think that it's not a bug, but feature request.

I have two datacenters joined with fast links, i have syncronous 
replication so server groups in two separate datacenters forms clusters.
if one campus burned with own fencing devices in a whole how i must fix 
this?
In some situations administrator needs of simple and fast manual 
confirmation or it's not a high availability.
