Ceph Cluster Migration
======================
This guide contains step by step instructions for manually migrating a StarlingX
deployment with a standard dedicated storage Ceph Cluster to a containerized Ceph
cluster deployed by Rook.

------------
Introduction
------------
In early releases of StarlingX, the backend storage cluster solution (Ceph) was
deployed directly on the host platform. In an upcoming release of StarlingX,
Ceph cluster will be containerized and managed by Rook, to improve operation
and maintenance efficiency.
This guide describes a method to migrate the Ceph cluster deployed with StarlingX
early releases to the newly containerized Ceph clusters using an upcoming StarlingX
release, while maintaining user data in |OSDs|.
---------------------
Prepare for migration
---------------------
StarlingX uses some :abbr:`HA (High Availability)` mechanisms for critical
service monitoring and recovering. To migrate Ceph monitor(s) and Ceph OSD(s),
the first step is to disable monitoring and recovery for Ceph services. This
avoids interrupting the migration procedure with service restarts.
*************************************
Disable StarlingX HA for Ceph service
*************************************
Disable monitoring and recovering for Ceph service by pmon and service manager.
#. Disable pmon monitoring for Ceph mon and Ceph osd on every host.
::
sudo rm -f /etc/pmon.d/ceph.conf
sudo /usr/local/sbin/pmon-restart pmon_cmd_port
#. Disable service manager's monitoring of Ceph manager on controller host.
::
sudo sm-unmanage service mgr-restful-plugin
Service (mgr-restful-plugin) is no longer being managed.
sudo sm-unmanage service ceph-manager
Service (ceph-manager) is no longer being managed.
sudo sm-deprovision service-group-member storage-monitoring-services ceph-manager
sudo sm-deprovision service-group-member storage-services mgr-restful-plugin
**********************************
Enable Ceph service authentication
**********************************
StarlingX disables Ceph authentication, but authentication is required for Rook.
Before migration, enable authentication for each daemon.
#. Enable authentication for Ceph mon and osd service.
::
ceph config set mon.storage-0 auth_cluster_required cephx
ceph config set mon.storage-0 auth_supported cephx
ceph config set mon.storage-0 auth_service_required cephx

***********************************************
Create configmap and secret for Rook deployment
***********************************************
Rook uses a configmap, ``rook-ceph-mon-endpoint``, and a secret,
``rook-ceph-mon``, to get cluster info. Create the configmap and secret with
the commands below.
::
export NAMESPACE=kube-system
export ROOK_EXTERNAL_CEPH_MON_DATA=a=192.188.204.3:6789
export ROOK_EXTERNAL_FSID=$(ceph fsid)
export ROOK_EXTERNAL_CLUSTER_NAME=$NAMESPACE
export ROOK_EXTERNAL_MAX_MON_ID=0
kubectl -n "$NAMESPACE" create secret generic rook-ceph-mon \
> --from-literal=cluster-name="$ROOK_EXTERNAL_CLUSTER_NAME" \
> --from-literal=fsid="$ROOK_EXTERNAL_FSID" \
> --from-literal=admin-secret="$ADMIN_KEY" \
> --from-literal=mon-secret="$MON_KEY"
secret/rook-ceph-mon created
kubectl -n "$NAMESPACE" create configmap rook-ceph-mon-endpoints \
> --from-literal=data="$ROOK_EXTERNAL_CEPH_MON_DATA" \
> --from-literal=mapping="$ROOK_EXTERNAL_MAPPING" \
> --from-literal=maxMonId="$ROOK_EXTERNAL_MAX_MON_ID"

**********************
Remove rbd-provisioner
**********************
The ``platform-integ-apps`` application deploys the helm chart
``rbd-provisioner``. This chart is unnecessary after Rook is deployed, remove
it with the command below.
::

For every host with an OSD device, create a configmap with the name
``rook-ceph-osd-<hostname>-config``. In the configmap, specify the OSD data
folder. In the example below, the Rook osd0 data path is ``/var/lib/ceph/osd0``.

Ceph monitor data movement
**************************
For Ceph monitor migration, the Rook deployed monitor pod will read monitor data
for host path ``/var/lib/ceph/mon-<id>/data``. For example, if only one monitor
pod is deployed, a monitor process named ``mon.a`` in the monitor pod will be
created and monitor data will be in the host path ``/var/lib/ceph/mon-a/data``.
Before migration, disable one monitor service and launch another monitor
specified with the ``--mon-data /var/lib/ceph/mon-a/data`` parameter. This will
migrate the monitor data to ``/var/lib/ceph/mon-a/data``.

Deploy Rook helm chart
----------------------
StarlingX creates a application for Rook deployment. After finishing the
preparation steps above, run the application to deploy Rook. To complete live
migration and keep Ceph services ready, you should migrate Ceph services in the
following order:
#. Exit the first Ceph monitor, ``mon.a``, and launch the Rook cluster with one
monitor pod. At this time, 2 monitor daemons and 1 monitor pod are running.
#. Migrate OSD pods one by one.
#. Finally, migrate 2 monitor daemons to complete the migration.
**************************************
Disable Ceph monitors and Ceph manager

Disable Ceph manager on host controller-0 and controller-1.
