Hi all, I deployed a ceph cluster with jewel in four physical machines. Three physical machines were used for OSD and each of them had eight OSDs. The left one was used to serve as a monitor. At first, everything worked well. By the reason of test, I stopped all the OSD daemon and double checked no OSD process running. After that, I executed ceph -s and got the following output: osdmap e164: 24 osds: 7 up, 7 in No matter how much time elapsed, the output didn't change. The expected output should be: osdmap e164: 24 osds: 0 up, 0 in I think it is the matter of synchronisation between OSDs and monitor Would you like you explain this strange phenomenon for me. Thanks a bunch in advance. -- 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
