查看安装系统的状态¶
此处，以三个节点的 kubernetes 集群为例，安装 HwameiStor 存储系统。
$ kubectl get node
NAME STATUS ROLES AGE VERSION
10-6-234-40 Ready control-plane,master 140d v1.21.11
10-6-234-41 Ready <none> 140d v1.21.11
10-6-234-42 Ready <none> 140d v1.21.11
查看 HwameiStor 系统组件¶
以下 Pod 必须在系统中正常运行:
$ kubectl -n hwameistor get pod

hwameistor-volume-evictor-5db99cf979-4674n 1/1 Running 0 23m
local-disk-manager和local-storage组件是以DaemonSets方式进行部署的，必须在每个节点上运行。
查看 HwameiStor CRD（即 API）¶
以下 HwameiStor CRD 必须安装在系统上。
$ kubectl api-resources --api-group hwameistor.io
NAME SHORTNAMES APIVERSION NAMESPACED KIND

localvolumesnapshots lvs hwameistor.io/v1alpha1 false LocalVolumeSnapshot
resizepolicies hwameistor.io/v1alpha1 false ResizePolicy
详情参见 CRD 表。
查看 LocalDiskNodes 和 LocalDisks¶
HwameiStor 自动扫描每个节点上的磁盘，并为每一块磁盘生成一个 CRD 资源 LocalDisk (LD)。 没有被使用的磁盘，其状态被标记为 PHASE: Available。
$ kubectl get localdisknodes
NAME FREECAPACITY TOTALCAPACITY TOTALDISK STATUS AGE
k8s-master Ready 28h
k8s-node1 Ready 28h
k8s-node2 Ready 28h
$ kubectl get localdisks

localdisk-da121e8f0dabac9ee1bcb6ed69840d7b k8s-node1 /dev/sda Bound 28h
查看 LocalStorageNodes 及存储池¶
HwameiStor 为每个存储节点创建一个 CRD 资源 LocalStorageNode (LSN)。 每个 LSN 将会记录该存储节点的状态，及节点上的所有存储资源，包括存储池、数据卷、及相关配置信息。
$ kubectl get lsn
NAME IP STATUS AGE
10-6-234-40 10.6.234.40 Ready 3m52s
10-6-234-41 10.6.234.41 Ready 3m54s
10-6-234-42 10.6.234.42 Ready 3m55s

查看 StorageClass¶
HwameiStor Operator 在完成 HwameiStor 系统组件安装和系统初始化之后，会根据系统配置 （例如：是否开启 HA 模块、磁盘类型等）自动创建相应的 StorageClass 用于创建数据卷。
$ kubectl get sc
