cephadm (curl master)/15.2.9:: how to add orchestration
Hi! After an initial bumpy bootstrapping (IMHO the defaults should be whatever is already defined in .ssh of the user and custom values setup with cli arguments) now i'm stuck adding any service/hosts/osds because apparently i lack orchestration .. the the documentation show a big "Page does not exist" see https://docs.ceph.com/en/latest/docs/octopus/mgr/orchestrator so, what is it and what options do i have? to set up it seems that is as easy as: ceph orch set backend I just started with ceph and i just want to start a ceph service (i cannot call it a cluster) on my desktop (with 2 dedicated osds) to get familiar also with usage. Thanks a lot! Adrian

did you call bootstrap with --skip-ssh? Might explain this. Don't know how you ended up with your url, but the correct one is:
$ ceph mgr module enable cephadm $ ceph orch set backend cephadm $ ceph cephadm set-ssh-config -i ... $ cephadm set-priv-key -i ... $ cephadm set-pub-key -i ... Then
https://docs.ceph.com/en/octopus/cephadm/install/#add-hosts-to-the-cluster
should get you going again. I'd recommend to avoid calling --skip-ssh to avoid this roundtrip. Setting the ssh configs via
works better typically.
.. the the documentation show a big "Page does not exist" see https://docs.ceph.com/en/latest/docs/octopus/mgr/orchestrator
so, what is it and what options do i have? to set up it seems that is as easy as: ceph orch set backend
I just started with ceph and i just want to start a ceph service (i cannot call it a cluster) on my desktop (with 2 dedicated osds) to get familiar also with usage.
Thanks a lot! Adrian

did you call bootstrap with --skip-ssh? Might explain this. yes.. i did a lot of tryout to make it work with the already existing keys and ~/.ssh/config .. quite frustrating ..
Don't know how you ended up with your url, but the correct one is:
https://docs.ceph.com/en/octopus/mgr/orchestrator/ this is the link presented by dashboard when goint to Hosts or Inventory and warning me that i lack orchestration and pointing me to this documentation link
$ ceph mgr module enable cephadm $ ceph orch set backend cephadm great thanks a lot!! i can now add OSDs..
$ ceph cephadm set-ssh-config -i ... $ cephadm set-priv-key -i ... $ cephadm set-pub-key -i ... i found that i can set these in the bootstrap...
Thanks a lot for help! Adrian

Hi all, I’m just testing a new cluster and after shutting down one of the hosts, when I bring it back up none of the OSD’s will restart. The services fail to start of the osd’s and systemctl status for the service states “failed with result ‘exit-code’” Where to start looking for the root cause?

Where does this link come from? Usually "latest" and an actual release name (octopus in this case) don't appear both in an docs url, so wherever you saw that particular url must have a broken reference. -- May the most significant bit of your life be positive.
