Thank you very much to all.

On the software side, it is running Queens release. The ceph-ansible
version is 3.1.6 and is using filestore with non-collocated setup.

Cody

need to include those changes in an environment file to reflect the

So I guess something may be wrong with fencing, but I have no idea what

Hi Michele,
It is great to know the latest progress on this subject. I am
currently running a 3-controller cluster in Queens. Later I will test
Rocky and will experiment on this new feature!
Thank you to all of you for the wonderful works!
