# How-to guides

This section contains guides to help you manage your already up and running Ceph cluster, taking you through the complete node lifecycle.

## [Installing and initialising Ceph](https://ubuntu.com/ceph/docs/howtos?format=md#p-79980-installing-and-initialising-ceph)

Perform a general install of Charmed Ceph access the web UI.

* [Installing Charmed Ceph](https://ubuntu.com/ceph/docs/install-ceph)
* [Installing Ceph dashboard](https://ubuntu.com/ceph/docs/install-dashboard)

## [Managing your cluster](https://ubuntu.com/ceph/docs/howtos?format=md#p-79980-managing-your-cluster)

To ensure the health of your cluster, you need to scale your OSDs and MONs up or down, or replace OSD disks by recreating a Ceph OSD disk within a Charmed Ceph deployment. Depending on your MAAS nodes, you may need to change your change block devices.

* [Adding OSDs](https://ubuntu.com/ceph/docs/adding-osds)
* [Adding MONs](https://ubuntu.com/ceph/docs/adding-mons)
* [Replacing OSD disks](https://ubuntu.com/ceph/docs/replacing-osd-disks)
* [Removing OSDs](https://ubuntu.com/ceph/docs/removing-osds)
* [Removing MONs](https://ubuntu.com/ceph/docs/removing-mons)
* [Enabling full disk encryption](https://ubuntu.com/ceph/docs/enabling-fde)

## [Multi-site operations](https://ubuntu.com/ceph/docs/howtos?format=md#p-79980-multi-site-operations)

Here we discuss setting up [RADOS Gateway multi-site replication](https://ubuntu.com/ceph/docs/multi-site-replication) in a charmed Ceph deployment. Native replication between ceph-radosgw applications is supported via `juju relations`. By default, both primary and secondary RGW applications accept write operations (i.e. active-active replication is configured).

* Setting up multi-site replication
* Recovering from an outage with multi-site replication
* Scaling down multi-site to single-site

## [Integrating Charmed Ceph with other tools](https://ubuntu.com/ceph/docs/howtos?format=md#p-79980-integrating-charmed-ceph-with-other-tools)

Ceph works together with other products; find out how to integrate Charmed Ceph with:

* [Kubernetes](https://ubuntu.com/ceph/docs/kubernetes)
* [LXD](https://ubuntu.com/ceph/docs/lxd)
* [OpenStack](https://ubuntu.com/ceph/docs/openstack)
* [VMware](https://ubuntu.com/ceph/docs/vmware)

## [Upgrading deployment software](https://ubuntu.com/ceph/docs/howtos?format=md#p-79980-upgrading-deployment-software)

There are three pieces of software in a Charmed Ceph deployment that can be upgraded:

1. [charms](https://ubuntu.com/ceph/docs/upgrading-charms)
2. [cluster node operating system](https://ubuntu.com/ceph/docs/upgrading-nodes)
3. [Ceph itself](https://ubuntu.com/ceph/docs/upgrading-ceph)

## [Security](https://ubuntu.com/ceph/docs/howtos?format=md#p-79980-security)

Secure your OSDs with full disk encryption, and report any security issue to the team.

* [Enabling full disk encryption](https://ubuntu.com/ceph/docs/enabling-fde)
* [Report security vulnerabilities](https://ubuntu.com/ceph/docs/report-security-vulnerabilities)
