Thank you for your question @ytwxy99. Sorry that you are having a problem.
I’m not sure I understand the situation. If mongodb is empty, was Juju bootstrapped correctly initially?
What steps did you take before you attempted disaster recovery?
@jameinel did a long post on the manual steps to restore in a disaster recovery scenario:
What type of restore scenarios are you interested in?
Hi，@timClicks. The situation is that the directory of ‘/var/lib/juju/’ will be removed when my mongodb data is new. For example, I detele a unit information in mongodb, then i restart my jujud service on the same agent’s host. After that operation , i found the ‘/var/lib/juju/agent/${unit}’ would be removed. Can u understand this situation?
This has been fixed in the later versions of Juju.
The removal of the directory was due to the agent getting a “permanently unable to login” error as its password (and old password) did not validate.
Now the agents are just stopped, not removed.
Okey，I got it. I will try it on later version of juju. Thanks
