Hi, What will happen when constructing a cluster of 10 host, but the hosts are gradually removed from the cluster one by one (in each step waiting Ceph status to become healthy), and reaches eventually to, say, 3 hosts ? In other words, is there any problem with having 10 osd configuration in the ceph.conf, but actually only 3 is up (the 7 are down and out) ? I assume that if the size of the replication is 3, we can turn off 2 osds at each time, and Ceph can recover itself to the healthy state. Is it the case ? Thanks in advance. regards, Yasu -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
