Hi Greg,
Sorry I didn't reserve the environment due to urgent needs.
However I think you are right because at that time I just purged all pools and
re-create them in a short time, thank you very much!
Sincerely,
Craig Chi

If this a kind of bug or just I was doing something wrong? Feel free to let>me
know if you need more information. Are you still seeing this? It certainly
sounds like a bug, but I think the output you're seeing could also happen if
you had some deleted pools which the OSDs hadn't been able to purge yet. -Greg
