I got the monitor started with cephadm and could run ceph-mon manually to get the mon service running again. Thanks for the hints along the way Robert 😊 //Jens -----Oprindelig meddelelse----- Fra: Robert Sander <r.sander@xxxxxxxxxxxxxxxxxxx> Sendt: Thursday, January 26, 2023 4:23 PM Til: ceph-users@xxxxxxx Emne: Re: ceph 16.2.10 cluster down Hi Jens, On 26.01.23 16:17, Jens Galsgaard wrote: > After removing the dead monitors with the monmaptool the mon container has vanished from podman. > So this somehow made things worse. You have not mentioned that you are running Ceph in containers. The procedure to repair the MON map may look a little bit different then. The documentation only shows the non-containerized procedure. Do you still have the systemd unit for the last working MON? Run "systemctl --all | grep mon" to look for it. If it is stop try to start it. Does the MON run? > Is it possible to create and add new monitors? Re-bootstrap the cluster in lack of better terms? It should be possible to restore the MON db using an exisiting OSD: https://docs.ceph.com/en/pacific/rados/troubleshooting/troubleshooting-mon/#recovery-using-osds This procedure would also have to be adapted for a containerized setup.
