+## Ceph 持久卷
+
+<!-- The Canonical Distribution of Kubernetes allows you to connect with durable
+storage devices such as [Ceph](http://ceph.com). When paired with the
+[Juju Storage](https://jujucharms.com/docs/2.0/charms-storage) feature you
+can add durable storage easily and across clouds. -->
+
+Canonical 的 Kubernetes 发行版允许添加持久化存储设备，例如 [Ceph](http://ceph.com)。
+配合 [Juju Storage](https://jujucharms.com/docs/2.0/charms-storage)功能，
+可以跨云平台，添加持久化存储。
+
+<!-- Deploy a minimum of three ceph-mon and three ceph-osd units. -->
+
+部署一个至少有三个 ceph-mon 和三个 ceph-osd 单元的存储池。
+
+```
+juju deploy cs:ceph-mon -n 3
+juju deploy cs:ceph-osd -n 3
+```
+
+<!-- Relate the units together: -->
+关联这些单元：
+
+```
+juju add-relation ceph-mon ceph-osd
+```
+
+<!-- List the storage pools available to Juju for your cloud: -->
+列出云上 Juju 可用的存储池：
+
+    juju storage-pools
+
+<!-- Output: -->
+输出：
+
+```
+Name     Provider  Attrs
+ebs      ebs
+ebs-ssd  ebs       volume-type=ssd
+loop     loop
+rootfs   rootfs
+tmpfs    tmpfs
+```
+
+{{< note >}}
+
+<!-- This listing is for the Amazon Web Services public cloud.
+Different clouds may have different pool names. -->
+
+注意列表使用的是 AWS，不同的云有不同的存储池名称。
+
+{{< /note >}}
+
+<!-- Add a storage pool to the ceph-osd charm by NAME,SIZE,COUNT: -->
+
+以 “名字,大小,数量”的格式往 ceph-osd charm 中添加存储池：
+
+```
+juju add-storage ceph-osd/0 osd-devices=ebs,10G,1
+juju add-storage ceph-osd/1 osd-devices=ebs,10G,1
+juju add-storage ceph-osd/2 osd-devices=ebs,10G,1
+```
+
+<!-- Next relate the storage cluster with the Kubernetes cluster: -->
+接下来将 Kubernetes 和存储集群相关联：
+
+```
+juju add-relation kubernetes-master ceph-mon
+```
+
+<!-- We are now ready to enlist
+[Persistent Volumes](/docs/concepts/storage/persistent-volumes/)
+in Kubernetes which our workloads can consume via Persistent Volume (PV) claims. -->
+
+
+现在我们可以在 Kubernetes 中列举可用的[持久卷](/docs/concepts/storage/persistent-volumes/)，
+集群中的负载可以通过 PVC 申领来使用这些持久卷。
+
+```
+juju run-action kubernetes-master/0 create-rbd-pv name=test size=50
+```
+
+<!-- This example created a "test" Rados Block Device (rbd) in the size of 50 MB.
+
+Use watch on your Kubernetes cluster like the following, you should see the PV
+become enlisted and be marked as available: -->
+
+本例中创建了 50 MB 大小的 “test” Rados 块设备 (rbd)。
+
+在 Kubernetes 集群上使用如下所示的 watch 命令，可以看到 PV 加入列表，并被标记可用的过程：
+
+    watch kubectl get pv
+
+<!-- Output: -->
+输出:
+
+```
+NAME CAPACITY   ACCESSMODES   STATUS    CLAIM              REASON    AGE
+
+test   50M          RWO       Available                              10s
+```
+
+<!-- To consume these Persistent Volumes, your pods will need an associated
+Persistent Volume Claim with them, and is outside the scope of this README.
+See the [Persistent Volumes](/docs/concepts/storage/persistent-volumes/)
+documentation for more information. -->
+
+要使用这些持久卷，pods 需要关联一个持久卷申领，这超出了本文档的讨论范围。
+参见[持久卷](/docs/concepts/storage/persistent-volumes/)获取更多信息。
