Hi David,
Thanks a lot for your quick response...
What are you doing that only allows you to add one at a time?
I'm trying to create a scrip for adding/removing a mon in my environment --> I want to execute it from a simple web page...
Thanks a lot!

There is nothing that will stop you from having an even number of mons (including 2). You just run the chance of getting into a split brain scenario. As long as you aren't planning to stay in that scenario, I don't see a problem with it. I have 3 mons in my home cluster and I've had to remove one before leaving me with 2 for a few hours while I re-provisioned the third and nothing funky happened.Most ways to deploy a cluster allow you to create the cluster with 3+ mons at the same time (inital_mons). What are you doing that only allows you to add one at a time?On Tue, Aug 15, 2017 at 12:22 PM Oscar Segarra <oscar.segarra@xxxxxxxxx> wrote:______________________________Hi,I'd like to test and script the adding monitors process adding one by one monitors to the ceph infrastructure.Is it possible to have two mon's running on two servers (one mon each) --> I can assume that mon quorum won't be reached until both servers are up.Is this right?I have not been able to find any documentation about the behaviour of the sistem with just two monitors (or an even number of them).thanks a lot._________________
