That is what I though. I am increasing debug to see where we are getting stuck. I am not sure if it is an issue deactivating or a rdlock issue.
Thanks if we discover more we will post a question with details.

The rank needs to come back, flush its journal, and then complete its deactivation. To get more help, you need to describe your environment, version of Ceph in use, relevant log snippets, etc. -- Patrick Donnelly |
