Hello!We, in our environment, need a shared file system for /var/lib/nova/instances and Glance image cache (_base)..Is anyone using CephFS for this purpose?When folks say CephFS is not production ready, is the primary concern stability/data-integrity or performance?Is NFS (with NFS-Ganesha) is better solution? Is anyone using it today?
Our primary concern about CephFS is about its stability; there are a couple of important known bugs and it has yet to see the string QA that would qualify it for general production use. Storing VM images is one of the use cases it might be okay for, but:
Why not use RBD? It sounds like that's what you want, and RBD is purpose-built for managing VM images and volumes!
