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?
This is good idea, MDS can eat as much memory as possible. And with two MDS'es you can setup standby-replay k
