Hello - I have a couple of questions on ceph cluster stability, even we follow all recommendations as below: - Having separate replication n/w and data n/w - RACK is the failure domain - Using SSDs for journals (1:4ratio) Q1 - If one OSD down, cluster IO down drastically and customer Apps impacted. Q2 - what is stability ratio, like with above, is ceph cluster workable condition, if one osd down or one node down,etc. Thanks Swami _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
