Ceph Cluster Migration for duplex system

This guide contains step by step instructions for manually migrating a StarlingX deployment with an all-in-one duplex 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 host-based Ceph cluster deployed with StarlingX early releases to the newly containerized Ceph clusters using an upcoming StarlingX release, while maintaining user data in OSDs.

The migration procedure maintains CEPH OSDs and data on OSDs. Although the procedure does result in hosted applications experiencing several minutes of service outage due to temporary loss of access to PVCs or virtual disks, due to the temporary loss of the ceph service.

Prepare for migration

StarlingX uses some HA 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

  1. Disable service manager’s monitoring of Ceph related service on both two controllers.

    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-unmanage service ceph-mon
Service (ceph-mon) is no longer being managed.
sudo sm-unmanage service cephmon-fs
Service (cephmon-fs) is no longer being managed.
sudo sm-unmanage service drbd-cephmon
Service (drbd-cephmon) is no longer being managed.
sudo sm-unmanage service ceph-osd
Service (ceph-osd) 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
sudo sm-deprovision service-group-member storage-services ceph-osd
sudo sm-deprovision service-group-member controller-services ceph-mon
sudo sm-deprovision service-group-member controller-services cephmon-fs
sudo sm-deprovision service-group-member controller-services drbd-cephmon

Enable Ceph service authentication

StarlingX disables Ceph authentication, but authentication is required for Rook. Before migration, enable authentication for each daemon.

  1. Enable authentication for Ceph mon and osd service.

    ceph config set mon.controller auth_cluster_required cephx
ceph config set mon.controller auth_supported cephx
ceph config set mon.controller auth_service_required cephx
ceph config set mon.controller auth_client_required cephx
ceph config set mgr.controller-0 auth_supported cephx
ceph config set mgr.controller-0 auth_cluster_required cephx
ceph config set mgr.controller-0 auth_client_required cephx
ceph config set mgr.controller-0 auth_service_required cephx
ceph config set mgr.controller-1 auth_supported cephx
ceph config set mgr.controller-1 auth_cluster_required cephx
ceph config set mgr.controller-1 auth_client_required cephx
ceph config set mgr.controller-1 auth_service_required cephx
ceph config set osd.0 auth_supported cephx
ceph config set osd.0 auth_cluster_required cephx
ceph config set osd.0 auth_service_required cephx
ceph config set osd.0 auth_client_required cephx
ceph config set osd.1 auth_supported cephx
ceph config set osd.1 auth_cluster_required cephx
ceph config set osd.1 auth_service_required cephx
ceph config set osd.1 auth_client_required cephx

  2. Generate client.admin key.

    ADMIN_KEY=$(ceph auth get-or-create-key client.admin mon 'allow *' osd 'allow *' mgr 'allow *' mds 'allow *')
echo $ADMIN_KEY
AQDRGqFea0cYERAAwYdhhle5zEbLLkYHWF+sDw==
MON_KEY=$(ceph auth get-or-create-key mon. mon 'allow *')
echo $MON_KEY
AQBbs79eM4/FMRAAbu4jwdBFVS1hOmlCdoCacQ==

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"
configmap/rook-ceph-mon-endpoint created

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.

sudo rm -rf /opt/platform/sysinv/20.01/.crushmap_applied
source /etc/platform/openrc
system application-remove platform-integ-apps

system storage-backend-delete 3fd0a407-dd8b-4a5c-9dec-8754d76956f4 --force

Update puppet system config.

sudo sysinv-puppet create-system-config

Remove script ceph.sh on both controllers.

sudo rm -rf /etc/services.d/controller/ceph.sh
sudo rm -rf /etc/services.d/worker/ceph.sh
sudo rm -rf /etc/services.d/storage/ceph.sh

Disable ceph osd on all storage hosts and create configmap for migration

  1. Login to controller host and run ceph-preshutdown.sh firstly.

    sudo ceph-preshutdown.sh

Login to the both controllers, disable the Ceph osd service, and create a journal file.

  1. Disable the Ceph osd service.

    sudo service ceph -a stop osd.1

  1. Sample osd-configmap.yaml file.

    apiVersion: v1
kind: ConfigMap
metadata:
  name: rook-ceph-osd-controller-0-config
  namespace: kube-system
data:
  osd-dirs: '{"/var/lib/ceph/ceph-0":0}'

apiVersion: v1
kind: ConfigMap
metadata:
  name: rook-ceph-osd-controller-1-config
  namespace: kube-system
data:
  osd-dirs: '{"/var/lib/ceph/ceph-1":1}'

  2. Apply yaml file for configmap.

    kubectl apply -f osd-configmap.yaml

configmap/rook-ceph-osd-controller-1-config created

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.

  1. Login to host controller-0 and disable service monitor.controller.

    sudo service ceph -a stop mon.controller
=== mon.controller-0 ===
Stopping Ceph mon.controller on controller-0...kill  291101...done

  2. Copy mon data to the /var/lib/ceph/mon-a/data folder.

    sudo mkdir -p /var/lib/ceph/mon-a/data/
sudo ceph-monstore-tool /var/lib/ceph/mon/ceph-controller/ store-copy /var/lib/ceph/mon-a/data/

  3. Update monmap in this copy of monitor data and update monitor info.

    sudo ceph-mon --extract-monmap monmap --mon-data /var/lib/ceph/mon-a/data/

Reboot controller-0 and controller-1

Reboot both two controllers, and wait for host to be available. After reboot, mount osd data partition on both controllers.

For example, on controller-0

sudo mount /dev/sdc1 /var/lib/ceph/ceph-0/osd0

On controller-1

sudo mount /dev/sdc1 /var/lib/ceph/ceph-1/osd1

Deploy Rook helm chart

StarlingX creates a application for Rook deployment. After finishing the preparation steps above, run the application to deploy Rook.

Apply rook-ceph application

  1. Assign a label for Ceph monitor and Ceph manager pod.

    source /etc/platform/openrc
system host-label-assign controller-0 ceph-mon-placement=enabled
+-------------+--------------------------------------+
| Property    | Value                                |

| label_value | enabled                              |
+-------------+--------------------------------------+

  2. Update override value for the rook-ceph-apps application with a created values.yaml file.

    values.yaml

    cluster:
  hostNetwork: true
