Hi, I am trying to get a very minimal Ceph cluster up and running (on ARM) and I'm wondering what is the smallest unit that I can run rados-bench on ? Documentation at (http://ceph.com/docs/next/start/quick-ceph-deploy/) seems to refer to 4 different nodes. Admin Node, Monitor Node and 2 OSD only nodes.
Can the Admin node be an x86 machine even if the deployment is ARM based? Or can the Admin Node and Monitor node co-exist. Finally, I'm assuming I can get by with only 1 independent OSD node. If that's possible, I can get by with 2 ARM systems only. Can someone please shed some light on whether this will work? Thanks Pankaj
