Than you say that if i get an initial connection to glusterfs1 and 
the day glusterfs1goes down but the gluster has a secondary node like 
the kvm itself switches withouth problems to second node?


I see this with the old version (fuse mounted) and i am not sure about
the kvm version.

Another question: tracing the writes i've seen that almost 85% of writes
appears on the first brick of the gluster bricks (3.4). With the old
version the writes was about 50% and 50%  (with two bricks).
The reads are OK 50-50
