Hi Bernhard,
I have my testcluster consisting two OSDs that also host MONs plus one to five MONs.
Are you saying that you have a total of 7 mons?
down the at last, not the other MON though (since - surprise - they are in this test szenario just virtual instances residing on some ceph rbds)
This seems to be your problem. When you shutdown the cluster, you haven't got those extra mons. In order to reach a quorum after reboot, you need to have more than half of yours mons running. If you have 5 or more mons in total, this means that the two physical servers running mons cannot reach quorum by themselves. I.e. you have 2 mons out of 5 running for example - it will not reach a quorum because you need at least 3 mons to do that. You need to either move mons to physical machines, or virtual instances not depending on the same Ceph cluster, or reduce the number of mons in the system to 3 (or 1). -- Jens Kristian Søgaard, Mermaid Consulting ApS, j...@mermaidconsulting.dk, http://wwww.mermaidconsulting.com/ _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
