Hello folks,
We're operating a small ceph test cluster made of 5 VMs, 1
monitor/manager, 3 osd and 1 radosgateway for
owncloud S3 external storage use. This works almost fine.
We're planning to use rbd too and get block device for a linux server.
In order to do that, we installed ceph-common packages
and created ceph.conf and ceph.keyring as explained at Basic Ceph Client
Setup — Ceph Documentation
<https://docs.ceph.com/en/pacific/cephadm/client-setup/>
(https://docs.ceph.com/en/pacific/cephadm/client-setup/)
This does not work.
Ceph seems to be installed
$ dpkg -l | grep ceph-common
ii ceph-common 16.2.9-1~bpo11+1 amd64 common
utilities to mount and interact with a ceph storage cluster
ii python3-ceph-common 16.2.9-1~bpo11+1 all Python 3
utility libraries for Ceph
$ ceph -v
ceph version 16.2.9 (4c3647a322c0ff5a1dd2344e039859dcbd28c830) pacific
(stable)
But, when using commands that interact with the cluster, we get this message
$ ceph -s
2022-07-08T15:51:24.965+0200 7f773b7fe700 -1 monclient(hunting):
handle_auth_bad_method server allowed_methods [2] but i only support [2,1]
[errno 13] RADOS permission denied (error connecting to the cluster)
We tried to insert these lines in ceph.conf
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
as explained in a former forum, but we still get the error message,
slightly different
$ ceph -s
2022-07-08T15:51:24.965+0200 7f773b7fe700 -1 monclient(hunting):
handle_auth_bad_method server allowed_methods [2] but i only support [2]
[errno 13] RADOS permission denied (error connecting to the cluster)
Does anyone have an idea ? .
The cluster was installed with ceph-deploy in Nautilus 14.2.21 on Debian
10.9, then upgraded in Octopus 15.2.16 with Ceph-deploy.
Then Debian was upgraded in 11.3 and ceph-deploy couldn't go further.
The las cluster upgrade was in Pacific 16.2.9, made with
Debian apt-get.
If you need more information ask us, we would be grateful to get some help.
JM
