Hi Mika, as i understand the situation, important is just that you have at least one MD running. You dont have quorum there, so its just about making sure that there is always at least one MD ready. I red, that for now, running multiple MDs active at the same time, might cause problems. So you should just have one active at the same time. The rest will be in standby and waiting the active one to die. -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 Am 24.03.2016 um 11:01 schrieb Mika c: > Hi cephers, > If I want to activate more than one mds node.
