Resent due to moderation when using web interface. Hi ceph users, We have a few clusters with quincy 17.2.6 and we are preparing to migrate from ceph-deploy to cephadm for better management. We are using Ubuntu20 with latest updates (latest openssh). While testing the migration to cephadm on a test cluster with octopus (v16 latest) we had no issues replacing ceph generated cert/key with our own CA signed certs (ECDSA). After upgrading to quincy the test cluster and test again the migration we cannot add hosts due to the errors below, ssh access errors specified a while ago in a tracker. We use the following type of certs: Type: ecdsa-sha2-nistp384-cert-v01@xxxxxxxxxxx user certificate The certificate works everytime when using ssh client from shell to connect to all hosts in the cluster. We do a ceph mgr fail every time we replace cert/key so they are restarted. ----- cephadm logs from mgr ------ Oct 06 09:23:27 ceph-m2 bash[1363]: Log: Opening SSH connection to 10.10.10.232, port 22 Oct 06 09:23:27 ceph-m2 bash[1363]: [conn=3] Connected to SSH server at 10.10.10.232, port 22 Oct 06 09:23:27 ceph-m2 bash[1363]: [conn=3] Local address: 10.10.12.160, port 51870 Oct 06 09:23:27 ceph-m2 bash[1363]: [conn=3] Peer address: 10.10.10.232, port 22 Oct 06 09:23:27 ceph-m2 bash[1363]: [conn=3] Beginning auth for user root Oct 06 09:23:27 ceph-m2 bash[1363]: [conn=3] Auth failed for user root Oct 06 09:23:27 ceph-m2 bash[1363]: [conn=3] Connection failure: Permission denied Oct 06 09:23:27 ceph-m2 bash[1363]: [conn=3] Aborting connection Oct 06 09:23:27 ceph-m2 bash[1363]: Traceback (most recent call last): Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/ssh.py", line 111, in redirect_log Oct 06 09:23:27 ceph-m2 bash[1363]: yield Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/ssh.py", line 90, in _remote_connection Oct 06 09:23:27 ceph-m2 bash[1363]: preferred_auth=['publickey'], options=ssh_options) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/lib/python3.6/site-packages/asyncssh/connection.py", line 6804, in connect Oct 06 09:23:27 ceph-m2 bash[1363]: 'Opening SSH connection to') Oct 06 09:23:27 ceph-m2 bash[1363]: File "/lib/python3.6/site-packages/asyncssh/connection.py", line 303, in _connect Oct 06 09:23:27 ceph-m2 bash[1363]: await conn.wait_established() Oct 06 09:23:27 ceph-m2 bash[1363]: File "/lib/python3.6/site-packages/asyncssh/connection.py", line 2243, in wait_established Oct 06 09:23:27 ceph-m2 bash[1363]: await self._waiter Oct 06 09:23:27 ceph-m2 bash[1363]: asyncssh.misc.PermissionDenied: Permission denied Oct 06 09:23:27 ceph-m2 bash[1363]: During handling of the above exception, another exception occurred: Oct 06 09:23:27 ceph-m2 bash[1363]: Traceback (most recent call last): Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 125, in wrapper Oct 06 09:23:27 ceph-m2 bash[1363]: return OrchResult(f(*args, **kwargs)) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/module.py", line 2810, in apply Oct 06 09:23:27 ceph-m2 bash[1363]: results.append(self._apply(spec)) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/module.py", line 2558, in _apply Oct 06 09:23:27 ceph-m2 bash[1363]: return self._add_host(cast(HostSpec, spec)) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/module.py", line 1434, in _add_host Oct 06 09:23:27 ceph-m2 bash[1363]: ip_addr = self._check_valid_addr(spec.hostname, spec.addr) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/module.py", line 1415, in _check_valid_addr Oct 06 09:23:27 ceph-m2 bash[1363]: error_ok=True, no_fsid=True)) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/module.py", line 615, in wait_async Oct 06 09:23:27 ceph-m2 bash[1363]: return self.event_loop.get_result(coro) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/ssh.py", line 56, in get_result Oct 06 09:23:27 ceph-m2 bash[1363]: return asyncio.run_coroutine_threadsafe(coro, self._loop).result() Oct 06 09:23:27 ceph-m2 bash[1363]: File "/lib64/python3.6/concurrent/futures/_base.py", line 432, in result Oct 06 09:23:27 ceph-m2 bash[1363]: return self.__get_result() Oct 06 09:23:27 ceph-m2 bash[1363]: File "/lib64/python3.6/concurrent/futures/_base.py", line 384, in __get_result Oct 06 09:23:27 ceph-m2 bash[1363]: raise self._exception Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/serve.py", line 1361, in _run_cephadm Oct 06 09:23:27 ceph-m2 bash[1363]: await self.mgr.ssh._remote_connection(host, addr) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/ssh.py", line 96, in _remote_connection Oct 06 09:23:27 ceph-m2 bash[1363]: raise Oct 06 09:23:27 ceph-m2 bash[1363]: File "/lib64/python3.6/contextlib.py", line 99, in __exit__ Oct 06 09:23:27 ceph-m2 bash[1363]: self.gen.throw(type, value, traceback) Oct 06 09:23:27 ceph-m2 bash[1363]: File "/usr/share/ceph/mgr/cephadm/ssh.py", line 123, in redirect_log Oct 06 09:23:27 ceph-m2 bash[1363]: raise HostConnectionError(msg, host, addr) Oct 06 09:23:27 ceph-m2 bash[1363]: cephadm.ssh.HostConnectionError: Failed to connect to ceph-m1 (10.10.10.232).
