Hello,
Thank you very much Joshua, it worked. I have set up three nodes with the cephadm tool, which was very easy. But I asked myself, what if node 1 goes down? Before cephadm I just could manage everything from the other nodes with the ceph commands. Now I'm a bit stuck, because this cephadm container is just running on one node. I've installed it on the second one, but i'm getting a "[errno 13] RADOS permission denied (error connecting to the cluster)". Do I need some special "cephadm" keyring from the first node? Which one? And where to put it? Caphadm might be an easy to handle solution, but for me as a beginner, the added layer is very complicated to get in. We are trying to build a new Ceph cluster (never got in touch with it before) but I might not go with octopus, but instead use nautilus with ceph-deploy. That's a bit easyer to understand, and the documentation out there is way better. Thanks in advance, Simon ________________________________ Von: Joshua Schmid <jsch...@suse.de> Gesendet: Dienstag, 5.
