I trying to make a High Availability file system with glusterfs 3.4 on
ubuntu 14.04
I configured the peers work fine, the replicate volume work good.

but I disconnect the network cable on the node-01( for make a test )
the volume glusterfs on the node-02 not keep mounted in the host node-02.

I need to make some configuration, or I´ma make something wrong ?
