While two mgrs is considered sufficient, more mgr daemons are
now allowed in case the admin wants even more fault tolerance
to the active mgr going down, in case multiple mgrs go down.
Up to five mgr pods will be allowed. All mgrs will be in
standby mode except one active mgr. All mgr pods have a sidecar
that will update their respective pod specs with the active
or passive label.

Rook
Rook is an open source cloud-native storage orchestrator, providing the platform, framework, and support for Ceph storage to natively integrate with cloud-native environments.
Ceph is a distributed storage system that provides file, block and object storage and is deployed in large scale production clusters.
Rook automates deployment and management of Ceph to provide self-managing, self-scaling, and self-healing storage services. The Rook operator does this by building on Kubernetes resources to deploy, configure, provision, scale, upgrade, and monitor Ceph.
The Ceph operator was declared stable in December 2018 in the Rook v0.9 release, providing a production storage platform for many years. Rook is hosted by the Cloud Native Computing Foundation (CNCF) as a graduated level project.
Quick Start Guide
Starting Ceph in your cluster is as simple as a few kubectl commands.
See our Quickstart guide to get started with the Ceph operator!
Designs
Ceph is a highly scalable distributed storage solution for block storage, object storage, and shared filesystems with years of production deployments. See the Ceph overview.
