Hi all, I'm having problem creating an osd using ceph-volume (by the way of cephadm). This is on an octopus installation with cephadm. So I use "cephadm shell" and then "ceph-volume" but got the following error: root@furry:/var/lib# ceph-volume lvm prepare --data /dev/sda --block.db /dev/vg/sda.db --dmcrypt Running command: /usr/bin/ceph-authtool --gen-print-key Running command: /usr/bin/ceph-authtool --gen-print-key Running command: /usr/bin/ceph --cluster ceph --name client.bootstrap-osd --keyring /var/lib/ceph/bootstrap-osd/ceph.keyring -i - osd new 29d95564-733d-4f2a-a2c8-1bb9ceb5a14b stderr: [errno 13] RADOS permission denied (error connecting to the cluster) --> RuntimeError: Unable to create a new OSD id if I pass the cluster ID, and use the correct key ring (using the client.admin keyring), I got a bit further root@furry:/var/lib# ceph-volume --cluster c258000c-f3e4-11ea-9ebe-c3c75e8e9028 lvm prepare --data /dev/sda --block.db /dev/vg/sda.db --dmcrypt Running command: /usr/bin/ceph-authtool --gen-print-key Running command: /usr/bin/ceph-authtool --gen-print-key Running command: /usr/bin/ceph --cluster c258000c-f3e4-11ea-9ebe-c3c75e8e9028 --name client.bootstrap-osd --keyring /var/lib/ceph/bootstrap-osd/c258000c-f3e4-11ea-9ebe-c3c75e8e9028.keyring -i - osd new aa13c362-c9cf-4d03-9a86-d6118fbc312c stderr: Error initializing cluster client: ObjectNotFound('RADOS object not found (error calling conf_read_file)',) --> RuntimeError: Unable to create a new OSD id Any idea on how to get pass these errors?
