Hello Brian, as long as you have at least one working MON, it's kind of easy to recover. Shutdown all MONs, modify the MONMAP by hand, leaving just one of the working MONs and then start it up. After that, redeploy the other mons to have your quorum and redundancy back again. You find more details and commands at https://docs.ceph.com/en/latest/rados/troubleshooting/troubleshooting-mon/#recovering-a-monitor-s-broken-monmap . -- Martin Verges Managing director Mobile: +49 174 9335695 E-Mail: martin.verges@xxxxxxxx Chat: https://t.me/MartinVerges croit GmbH, Freseniusstr. 31h, 81247 Munich CEO: Martin Verges - VAT-ID: DE310638492 Com. register: Amtsgericht Munich HRB 231263 Web: https://croit.io YouTube: https://goo.gl/PGE1Bx Am Sa., 10.
