I solved the mount gfs filesystem.
I forgot to run "fence_ack_manual -n vserver1.teste.br".
Now I can mount the gfs partition.
Now I have other problem.
One node appear offline to other node.
When I use command line to migrate online the vm to node 2 it's ok.
And of node 2 to node 1, too.
Appear this in messages file.
