We now run all the daemon with a new option from Nautilus 14.2.1 which
allows us to tell to a daemon to not log on file. However, we can decide
to activate logging by editing the configuration flag 'log_to_file' via
the centralized config store like this for a particular daemon:
ceph config set mon.a log_to_file true
This is useful when a daemon keeps crashing and we want to collect log
files on the system.

Make the Ceph operator more cautious about when it decides to remove
nodes from the Rook-Ceph cluster which are acting as osd hosts.
When `useAllNodes` is set to `true` we assume that the user wants to
have the most hands-off experience. Node removals are allowed when a
node is delted from Kubernetes and when a node has its taints/affinities
modified by the user (but not by automatic k8s modification as much as
possible).
When `useAllnodes` is set to `false` the only time a node is removed is
if it is removed from the Ceph cluster definition.

need to remove the manual namespace creation from

The current document is too old and it has
a reference to the master branch(earlier
master branch referred to csi-v0.3.0).
This PR updated the snapshot document
wrt to the changes required for csi-v1.0.0

The RBAC is tedious to copy everywhere with the cluster.yaml and is confusing to newcomers.
The common resources are now factored into the operator-common.yaml for the common scenario
of creating a single cluster. Examples are now added for configuration of the operator
and cluster crds to provide a more complete set.

The RBD module is an important prerequisite for Rook Ceph. It is mentioned as a possible problem on the Common Issues page, but that is the ambulance at the bottom of the cliff 😄. We should mention the perquisite for new users, tell them how to check, and note any major Kubernetes-as-a-service providers that do not have the RBD module.

The examples folder has Service examples but no Ingress examples. This example Ingress is important because it demonstrates how to configure and Ingress that will work with the self-signed certificate the `rook-ceph` installs. The Service name and Namespace matches the default `rook-ceph` install.

The desired number of mons could change depending on the number of nodes in a cluster.
For example, three mons would be the min number of mons in a production cluster with at
least three nodes. If there are five or more nodes, the number of mons could increase
to five in order to increase the failure tolerance to two nodes.
This is accomplished by a new setting in the cluster CRD preferredCount. If the number
of hosts exceeds preferredCount, more mons are added to quorum. If the number
of hosts drops below the preferred count, the operator would reduce the quorum size to
the smaller desired count.

Configure the Ceph rgw daemon completely from the operator a la the
recent changes to the Ceph mon, mgr, and mds operators.
Create the rgw deployment or daemonset first, and then create the
keyring secret for the object store with its owner reference as the
corresponding deployment or daemonset. When the replication controller
is deleted, the secret is also deleted.
The RGW's mime.types file is now stored in a configmap with a different
file created for each object store. This is primarily just a means to
get the mime.types file into the rgw pod, but the added benefit is that
the administrator can modify the configmap, which could reduce
susceptibility to file type execution vulnerabilities (worst case).
