I have a network adapter reserved and direct connected from the two server with dedicated IP 172.16.3.1/30 and 172.16.3.2/30, named via /etc/hosts virt1.local and virt2.local
In this logs I see also the real server name ( ... HOST:s-virt1.realdomain.it-PC_NAME: ...) which has another IP on another network.
Now this cluster is in production and support some VM.
What is the bes way to solve this dangerous situation without risk?
Many thanks
Dario

No, it's not normal.Go to the virt2 and in /var/log/gluster directory you will find 'bricks' . Check the logs in bricks for more information.Best Regards,Strahil Nikolov
