I'm pretty sure it's an asyncssh error. I've never seen the issue, but seems related. https://github.com/ronf/asyncssh/issues/725 On Fri, Mar 28, 2025, 11:43 Eugen Block <eblock@nde.ag> wrote:
Hi,
you can use any pastebin to share verbose logs. I tried to find something in the code related to the message (Server not responding to keepalive), but couldn't find anything. Maybe it's not Ceph related? But I'm also not a dev, so I might just misunderstand.
Zitat von Reid Kelley <reid@drawbridgedigital.com>:
Setting up a new cluster on fresh ubuntu 24.04 hosts using cephadm. The first 5 hosts all added without issue, but the next N hosts all throw the same error when adding through the dashboard or through ceph orch add... All hosts have ssh access, docker and all base requirements confirmed.
Command: ceph orch host add foxtrot 10.1.20.16
Error: Error EINVAL: check-host failed: Unable to write
foxtrot:/var/lib/ceph/260974b7-fbb6-11ef-911a-107c6152e887/cephadm.c6d8d2eb72a60267f2844dd3167700619f1207413db7701f1827abf652e86a11:
Server not responding to keepalive
There is a long stack trace that references asyncssh and the /lib/python3.9/site-packages/asyncssh/sftp.py file. Happy to share but not sure best way in the mailing list.
Thanks for any help and advice. -Reid
