Dear ceph users, I'm in the very initial phase of planning a ceph cluster an have a question regarding the RAM recommendation for an MDS. According to the ceph docs the minimum amount of RAM should be "1 GB minimum per daemon". Is this per OSD in the cluster or per MDS in the cluster? I plan to run 3 ceph-mon on 3 dedicated machines and would like to run 3 ceph-msd on these machines as well. The raw capacity of the cluster should be ~1.9PB. Would 64GB of RAM then be enough for the ceph-mon/ceph-msd nodes? Thanks Dietmar -- _________________________________________ D i e t m a r R i e d e r
