Hi There is a little thing I do not understand in the election of the master.
I have two geographic site (Paris, Versailles). the quorum is (n / 2) +1 if I have two servers in each site the quorum is (4/2) +1 = 3 so if I have a blackout on the site (eg fire) I do not have the quorum because I have only two servers if I have two server on a site and on the other the quorum is (3/2) +1 = 2 so if I have a blackout on first site (eg fire) I do not have a quorum because I have only one server It is impossible to secure the cluster?
