一.PV及PVC概述

1>.什么是persistentVolume(持久卷,简称PV)

[root@test110.yinzhengjie.org.cn ~]# cat /etc/exports
/yinzhengjie/data/volume1    172.200.0.0/21(rw,no_root_squash)
/yinzhengjie/data/volume2    172.200.0.0/21(rw,no_root_squash)
/yinzhengjie/data/volume3    172.200.0.0/21(rw,no_root_squash)
[root@test110.yinzhengjie.org.cn ~]# 
[root@test110.yinzhengjie.org.cn ~]# cat /etc/exports
  所谓的PV其实就是存储卷的意思,它可并不是和存储系统一一对应的关系哟,它对应的是存储系统的一个存储空间对应一个pv。

  我们以NFS的配置文件为例(参考上面的"/etc/exports"文件),"/yinzhengjie/data/volume1"其实对应的就是一个pv,"/yinzhengjie/data/volume2"和"/yinzhengjie/data/volume3"均各自对应一个pv。

2>.什么是persistentVolumeClaim(简称PVC)

  我们知道Kubernetes集群有两个级别,一种是名称空间,一种是集群资源。Pod属于名称空间的资源,而pv则是集群资源,如果名称空间的Pod想要使用pv,则需要将pv注册(说白了就是请求占用pv)到和该Pod相同的名称空间中,我们称之为persistentVolumeClaim(简称PVC)。

  所谓的PVC我们可以理解为PV的一个客户端,pvc和pv之间没有直接联系,一个PVC可以绑定一个pv,此时pvc才会该pv建立关系,该pv就处于binding状态。与此同时,一个名称空间的pvc占用了某个pv,则该pv不能被其它名称的空间占用。
 
  如果一个pv没有被任何pvc所绑定,那么该pv就处于available。

  温馨提示:
    我们在Pod上使用persistentVolumeClaim类型的存储卷来使用pvc,我们在Pod上定义了pvc的存储卷容器是不能直接使用它的,Pod中的容器需要使用"
volumeMounts"字段去挂载存储卷。
[root@master200.yinzhengjie.org.cn ~]# kubectl explain pods.spec.volumes.persistentVolumeClaim
KIND:     Pod
VERSION:  v1

RESOURCE: persistentVolumeClaim <Object>

DESCRIPTION:
     PersistentVolumeClaimVolumeSource represents a reference to a
     PersistentVolumeClaim in the same namespace. More info:
     https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

     PersistentVolumeClaimVolumeSource references the user's PVC in the same
     namespace. This volume finds the bound PV and mounts that volume for the
     pod. A PersistentVolumeClaimVolumeSource is, essentially, a wrapper around
     another type of volume that is owned by someone else (the system).

FIELDS:
   claimName    <string> -required-
     ClaimName is the name of a PersistentVolumeClaim in the same namespace as
     the pod using this volume. More info:
     https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

   readOnly    <boolean>
     Will force the ReadOnly setting in VolumeMounts. Default false.

[root@master200.yinzhengjie.org.cn ~]# 
[root@master200.yinzhengjie.org.cn ~]# kubectl explain pods.spec.volumes.persistentVolumeClaim

3>.pvc的访问模式(accessModes)取决于pv

  一般存储系统的访问模型大致分为以下三种:
    单路读写(ReadWriteOnce,简称为RWO)
    多路只读(ReadOnlyMany,简称为ROM)
    多路读写(ReadWriteMany,简称为RWM)

  同一个pvc是否可以同时被多个Pod同时使用呢?
    这取决于pv是否支持多路读写(比如NFS就支持多路客户端同时读写访问,而Iscsi这种块级别的存储则不支持多路读写)。如果pv支持多路读写,那么与之绑定的pvc也支持多路读写,也就是说支持多个Pod同时绑定到同一个pvc上,反之则反。

4>.pv的回收(reClaim)策略

  pv除了上面我们所说的binding和available两种状态外还有两种就是回收(reClaim)状态。

  pv的回收(reClaim)策略有以下三种:
    Recycle(deprecated,已弃用):
      删除pvc时,只把pv上的数据删除,也就是说并没有把pv资源删除,该策略已被Google废弃,在后续版本可能会被移除,因此不推荐使用。
    Delete:
      删除PVC时,也会同时删除pv资源。
    Retain:
      删除pvc时,pv和pv上的数据军均不删除,对于重要的数据生产环境推荐使用这种策略。

5>.PVC的生命周期

  pv的供给(Provisioning)方式:
    static:
      说白了就得咱们人工手动创建pv,比如NFS等
    dynamic:
      说白了就是无序人工介入,存储系统自动就支持pv的创建啦,比如Cephfs等,它是需要借助于存储类(StorageClass,简称SC),当创建pvc时,pvc会向SC请求,SC已经内置了如何连接pv的方式。

  pvc的生命周期分为四种状态:     Provisioning(即PV是如何创建的,NFS默认只支持静态创建pv,而cephfs是支持动态创建pv)     Binding(绑定了PV)     Using(Pod在使用pvc)     Reclaiming(回收状态)。   博主推荐阅读:     https:

[root@test110.yinzhengjie.org.cn ~]# systemctl start nfs
nfs无法启动:
  如果你nfs启动失败很可能是由于rpcbind服务没有启动导致的。因为nfs服务是依赖于rpc服务的,我的报错信息如下所示:
    Feb 10 18:36:52 test110.yinzhengjie.org.cn systemd[1]: rpcbind.socket failed to listen on sockets: Address family not supported by protocol

解决方案:
    经查阅资料是需要禁用ipv6,修改rpc的配置文件后并重启rpcbind服务,之后nfs可以成功启动啦。具体操作如下所示。

[root@test110.yinzhengjie.org.cn ~]#  find /etc/ -name '*rpcbind.socket*'
/etc/systemd/system/sockets.target.wants/rpcbind.socket
[root@test110.yinzhengjie.org.cn ~]# 
[root@test110.yinzhengjie.org.cn ~]# 
[root@test110.yinzhengjie.org.cn ~]# vim /etc/systemd/system/sockets.target.wants/rpcbind.socket
[root@test110.yinzhengjie.org.cn ~]# 
[root@test110.yinzhengjie.org.cn ~]# cat /etc/systemd/system/sockets.target.wants/rpcbind.socket

[root@test110.yinzhengjie.org.cn ~]# systemctl restart rpcbind.socket 
[root@test110.yinzhengjie.org.cn ~]# 
[root@test110.yinzhengjie.org.cn ~]# systemctl start nfs
[root@test110.yinzhengjie.org.cn ~]# 
"rpcbind.socket failed to listen on sockets: Address family not supported by protocol"报错解决方案,如果NFS正常启动的小伙伴可忽略本条记录。

2>.在K8S集群的每一个节点安装nfs客户端驱动

8>.删除pvc注意事项

  如下图所示,当有Pods在使用pvc时,我们无法是无法手动删除pvc的,这是官方的提出的一种存储保护机制。

  博主推荐阅读:
    https://kubernetes.io/docs/concepts/storage/persistent-volumes/#storage-object-in-use-protection

  想要删除pvc得确保没有Pods使用pvc资源,如果把正在使用pvc的所有Pods资源删除掉,此时就可以理解删除pvc了,如下图所示。

  删除pvc后,如果pvc的删除策略是"Retain",虽然删除pvc是成功了,但并不会删除pv资源及其所对应的存储系统中的数据,我们需要手动删除。

 

三.使用存储类案例

[root@master200.yinzhengjie.org.cn ~]# kubectl explain sc
KIND:     StorageClass
VERSION:  storage.k8s.io/v1

DESCRIPTION:
     StorageClass describes the parameters for a class of storage for which
     PersistentVolumes can be dynamically provisioned. StorageClasses are
     non-namespaced; the name of the storage class according to etcd is in
     ObjectMeta.Name.

FIELDS:
   allowVolumeExpansion    <boolean>
     AllowVolumeExpansion shows whether the storage class allow volume expand

   allowedTopologies    <[]Object>
     Restrict the node topologies where volumes can be dynamically provisioned.
     Each volume plugin defines its own supported topology specifications. An
     empty TopologySelectorTerm list means there is no topology restriction.
     This field is only honored by servers that enable the VolumeScheduling
     feature.

   apiVersion    <string>
     APIVersion defines the versioned schema of this representation of an
     object. Servers should convert recognized schemas to the latest internal
     value, and may reject unrecognized values. More info:
     https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

   kind    <string>
     Kind is a string value representing the REST resource this object
     represents. Servers may infer this from the endpoint the client submits
     requests to. Cannot be updated. In CamelCase. More info:
     https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

   metadata    <Object>
     Standard object's metadata. More info:
     https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

   mountOptions    <[]string>
     Dynamically provisioned PersistentVolumes of this storage class are created
     with these mountOptions, e.g. ["ro", "soft"]. Not validated - mount of the
     PVs will simply fail if one is invalid.

   parameters    <map[string]string>
     Parameters holds the parameters for the provisioner that should create
     volumes of this storage class.

   provisioner    <string> -required-
     Provisioner indicates the type of the provisioner.

   reclaimPolicy    <string>
     Dynamically provisioned PersistentVolumes of this storage class are created
     with this reclaimPolicy. Defaults to Delete.

   volumeBindingMode    <string>
     VolumeBindingMode indicates how PersistentVolumeClaims should be
     provisioned and bound. When unset, VolumeBindingImmediate is used. This
     field is only honored by servers that enable the VolumeScheduling feature.

[root@master200.yinzhengjie.org.cn ~]# 
[root@master200.yinzhengjie.org.cn ~]# kubectl explain sc
  存储类是为动态供给pv的,默认情况下,nfs是不支持动态供给的,但是可以通过插件实现让nfs也支持动态供给pv哟,参考连接:
