Hello, On my small Octopus 6 nodes cluster I have only 8 GB per node available and I am co-locating the active and standby MDS on two out of the 3 OSD nodes. But because memory is tight (8GB per node max, limited due to hardware constraints) I was thinking to add two new 8GB nodes dedicated only for MDS so they can benefit of more RAM. So my question is, is this a good idea? Are there any downsides of having MDS active and passive on two dedicated nodes? Regards, Mabi
