While there have been NFS gateways over CephFS for a long time, scaling
that service across multiple nodes has always been a challenge. Recently,
a new recovery backend was merged into the nfs-ganesha userland NFS
server that allows a cluster of NFS servers to coordinate their recovery
periods using a shared RADOS object, allowing us to scale out a cluster
of NFS servers in a loosely-coupled fashion on top of CephFS.

This presentation will cover some basics about NFS recovery, how we solved
the problem of coordinating the recovery across a cluster of NFS servers,
and some practical deployment scenarios.
