============================================================
Configure Ceph File System for Internal Ceph Storage Backend
============================================================
CephFS \(Ceph File System\) is a highly available, mutli-use, performant file
store for a variety of applications, built on top of Ceph's Distributed Object
Store \(RADOS\).
.. rubric:: |context|
CephFS provides the following functionality:
.. _configure-ceph-file-system-for-internal-ceph-storage-backend-ul-h2b-h1k-x4b:
- Enabled by default \(along with existing Ceph RDB\)
- Highly available, multi-use, performant file storage
- Scalability using a separate RADOS pool for the file's metadata
- Metadata using Metadata Servers \(MDS\) that provide high availability and
scalability
- Deployed in HA configurations for all |prod| deployment options
- Integrates **cephfs-provisioner** supporting Kubernetes **StorageClass**
- Enables configuration of:
- **PersistentVolumeClaim** \(|PVC|\) using **StorageClass** and
ReadWriteMany accessmode
- Two or more application pods mounting |PVC| and reading/writing data to it
CephFS is configured automatically when a Ceph backend is enabled and provides
a Kubernetes **StorageClass**. Once enabled, every node in the cluster that
serves as a Ceph monitor will also be configured as a CephFS Metadata Server
\(MDS\). Creation of the CephFS pools, filesystem initialization, and creation
of Kubernetes resource is done by the **platform-integ-apps** application,
using **cephfs-provisioner** Helm chart.
When applied, **platform-integ-apps** creates two Ceph pools for each storage
backend configured, one for CephFS data and a second pool for metadata:
.. _configure-ceph-file-system-for-internal-ceph-storage-backend-ul-jp2-yn2-x4b:
- **CephFS data pool**: The pool name for the default storage backend is
**kube-cephfs-data**
- **Metadata pool**: The pool name is **kube-cephfs-metadata**
When a new storage backend is created, a new CephFS data pool will be
created with the name **kube-cephfs-data-** \<storage\_backend\_name\>, and
the metadata pool will be created with the name
**kube-cephfs-metadata-** \<storage\_backend\_name\>. The default
filesystem name is **kube-cephfs**.
When a new storage backend is created, a new filesystem will be created
with the name **kube-cephfs-** \<storage\_backend\_name\>.
For example, if the user adds a storage backend named, 'test',
**cephfs-provisioner** will create the following pools:
.. _configure-ceph-file-system-for-internal-ceph-storage-backend-ul-i3w-h1f-x4b:
- kube-cephfs-data-test
- kube-cephfs-metadata-test
Also, the application **platform-integ-apps** will create a filesystem **kube
cephfs-test**.
If you list all the pools in a cluster with 'test' storage backend, you should
see four pools created by **cephfs-provisioner** using **platform-integ-apps**.
Use the following command to list the CephFS |OSD| pools created.
.. code-block:: none
$ ceph osd lspools
.. _configure-ceph-file-system-for-internal-ceph-storage-backend-ul-nnv-lr2-x4b:
- kube-rbd
- kube-rbd-test
- **kube-cephfs-data**
- **kube-cephfs-data-test**
- **kube-cephfs-metadata**
- **kube-cephfs-metadata-test**
Use the following command to list Ceph File Systems:
.. code-block:: none
$ ceph fs ls
name: kube-cephfs, metadata pool: kube-cephfs-metadata, data pools: [kube-cephfs-data ]
name: kube-cephfs-silver, metadata pool: kube-cephfs-metadata-silver, data pools: [kube-cephfs-data-silver ]
:command:`cephfs-provisioner` creates in a Kubernetes cluster, a
**StorageClass** for each storage backend present.
These **StorageClass** resources should be used to create
**PersistentVolumeClaim** resources in order to allow pods to use CephFS. The
default **StorageClass** resource is named **cephfs**, and additional resources
are created with the name \<storage\_backend\_name\> **-cephfs** for each
additional storage backend created.
For example, when listing **StorageClass** resources in a cluster that is
configured with a storage backend named 'test', the following storage classes
are created:
.. code-block:: none
$ kubectl get sc
NAME PROVISIONER RECLAIM.. VOLUME.. ALLOWVOLUME.. AGE
cephfs ceph.com/cephfs Delete Immediate false 65m
general (default) ceph.com/rbd Delete Immediate false 66m
test-cephfs ceph.com/cephfs Delete Immediate false 65m
test-general ceph.com/rbd Delete Immediate false 66m
All Kubernetes resources \(pods, StorageClasses, PersistentVolumeClaims,
configmaps, etc.\) used by the provisioner are created in the **kube-system
namespace.**
.. note::
Multiple Ceph file systems are not enabled by default in the cluster. You
can enable it manually, for example, using the command; :command:`ceph fs
flag set enable\_multiple true --yes-i-really-mean-it`.

Persistent Volume Claim \(PVC\)
-------------------------------
.. rubric:: |context|
If you need to create a Persistent Volume Claim, you can create it using
**kubectl**. For example:
.. _configure-ceph-file-system-for-internal-ceph-storage-backend-ol-lrh-pdf-x4b:
#. Create a file named **my\_pvc.yaml**, and add the following content:
.. code-block:: none

apiVersion: v1
metadata:
name: claim1

spec:
storageClassName: cephfs
accessModes:
- ReadWriteMany
resources:
requests:
storage: 1Gi
#. To apply the updates, use the following command:
.. code-block:: none
$ kubectl apply -f my_pvc.yaml
#. After the |PVC| is created, use the following command to see the |PVC|
bound to the existing **StorageClass**.
.. code-block:: none
$ kubectl get pvc -n kube-system
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
claim1 Boundpvc.. 1Gi RWX cephfs
#. The |PVC| is automatically provisioned by the **StorageClass**, and a |PVC|
is created. Use the following command to list the |PVC|.
.. code-block:: none
$ kubectl get pv -n kube-system
NAME CAPACITY ACCESS..RECLAIM.. STATUS CLAIM STORAGE.. REASON AGE
pvc-5.. 1Gi RWX Delete Bound kube-system/claim1 cephfs 26s
#. Create Pods to use the |PVC|. Create a file my\_pod.yaml:
.. code-block:: none
kind: Pod
apiVersion: v1
metadata:
name: test-pod
namespace: kube-system
spec:
containers:
- name: test-pod
image: gcr.io/google_containers/busybox:1.24
command:
- "/bin/sh"

volumeMounts:

mountPath: "/mnt"
restartPolicy: "Never"

#. Apply the inputs to the **pod.yaml** file, using the following command.
.. code-block:: none
$ kubectl apply -f my_pod.yaml
