Description Michaela Lang 2022-08-04 17:35:10 UTC
Description of problem:
Exception reporting to generic

Version-Release number of selected component (if applicable):
5.1


How reproducible:
everytime


Steps to Reproduce:
1. setup a Ceph cluster
2. prepare a host to be added to the cluster
3. do not configure "NOPASSWD" in sudoers file for the cephorch (cephadm configured) user
3.1 echo "${CEPHUSER} ALL=(ALL) ALL" > /etc/sudoers.d/cephorch
4. cephadm shell ceph orch host add node1 127.0.0.1 _admin

Actual results:
Can't communicate with remote host `127.0.0.1`, possibly because python3 is not installed there: cannot send (already closed?)


Expected results:
Added host 'node1' with addr '127.0.0.1'


Additional info:
Reason for the issue is comming from sudo with password closes the I/O and execnet fails which is catched by cephadm/ssh.py only with a generic error message. This leads to difficult debugging even though, the procedure and documentation for setting up is correct and mentioning NOPASSWD in sudoers as only supported way.

I additionally created a pull request upstream as well https://github.com/ceph/ceph/pull/47464.

I've checked out the posted PR. It looks good other than some stuff with the commit message.
