Going to take another stab at this...
We have a development environment–made up of VMs–for developing and testing
the deployment tools for a particular service that depends on cephfs for
sharing state data between hosts. In production we will be using filestore
OSDs because of the very low volume
I'm in the process of updating some development VMs that use ceph-fs. It

be on the look out for.
The current situation is that I've inherited res
