Hi, I just retried without the single-host option and it worked. Also everything under /tmp/var belongs to root in my case. Unfortunately, I can't use the curl-based cephadm but the contents are identical, I compared. Not sure what it could be at the moment. Zitat von Ben <ruidong.gao@gmail.com>:
Hi, It is uos v20(with kernel 4.19), one linux distribution among others. no matter since cephadm deploys things in containers by default. cephadm is pulled by curl from Quincy branch of github.
I think you could see some sort of errors if you remove parameter --single-host-defaults.
More investigation shows it looks like a bug with cephadm. during the deploying procedure ,/tmp/var/lib/ceph/ad3a132e-e9ee-11ed-8a19-043f72fb8bf9/cephadm.059bfc99f5cf36ed881f2494b104711faf4cbf5fc86a9594423cc105cafd9b4e.new is created through sudo ssh session remotely(with owner of root) and /tmp/var/lib/ceph/ad3a132e-e9ee-11ed-8a19-043f72fb8bf9/ is changed to owner of ssh user deployer. The correct thing to do instead is, /tmp/var/ be changed to the owner deployer recursively so that following scp can have access permission. I will see if having time to wire up a PR to fix it.
Thanks for help on this. Ben

Hi,
could you provide some more details about your host OS? Which cephadm version is it? I was able to bootstrap a one-node cluster with both 17.2.5 and 17.2.6 with a non-root user with no such error on openSUSE Leap 15.4:
quincy:~ # rpm -qa | grep cephadm cephadm-17.2.6.248+gad656d572cb-lp154.2.1.noarch

Hi,
with following command:
sudo cephadm --docker bootstrap --mon-ip 10.1.32.33 --skip-monitoring-stack --ssh-user deployer the user deployer has passwordless sudo configuration. I can see the error below:

Any ideas on this?
