If you have a small cluster, without host redundancy, you are still able to configure this in Ceph to be handled correctly by adding a drive failure domain between host and OSD level. So yes you need to change more then just failure-domain=OSD, as this would be a problem. However it is absolutely the same as to having multiple OSDs per NVMe as some people do it. -- 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., 13.
