# 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。 ```console $ 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 140d v1.21.11 10-6-234-42 Ready 140d v1.21.11 ``` ## 查看 HwameiStor 系统组件以下 Pod 必须在系统中正常运行: ```console $ kubectl -n hwameistor get pod NAME READY STATUS RESTARTS AGE drbd-adapter-k8s-master-rhel7-gtk7t 0/2 Completed 0 23m drbd-adapter-k8s-node1-rhel7-gxfw5 0/2 Completed 0 23m drbd-adapter-k8s-node2-rhel7-lv768 0/2 Completed 0 23m hwameistor-admission-controller-dc766f976-mtlvw 1/1 Running 0 23m hwameistor-apiserver-86d6c9b7c8-v67gg 1/1 Running 0 23m hwameistor-auditor-54f46fcbc6-jb4f4 1/1 Running 0 23m hwameistor-exporter-6498478c57-kr8r4 1/1 Running 0 23m hwameistor-failover-assistant-cdc6bd665-56wbw 1/1 Running 0 23m hwameistor-local-disk-csi-controller-6587984795-fztcd 2/2 Running 0 23m hwameistor-local-disk-manager-7gg9x 2/2 Running 0 23m hwameistor-local-disk-manager-kqkng 2/2 Running 0 23m hwameistor-local-disk-manager-s66kn 2/2 Running 0 23m hwameistor-local-storage-csi-controller-5cdff98f55-jj45w 6/6 Running 0 23m hwameistor-local-storage-mfqks 2/2 Running 0 23m hwameistor-local-storage-pnfpx 2/2 Running 0 23m hwameistor-local-storage-whg9t 2/2 Running 0 23m hwameistor-pvc-autoresizer-86dc79d57-s2l68 1/1 Running 0 23m hwameistor-scheduler-6db69957f-r58j6 1/1 Running 0 23m hwameistor-ui-744cd78d84-vktjq 1/1 Running 0 23m 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。 ```console $ kubectl api-resources --api-group hwameistor.io NAME SHORTNAMES APIVERSION NAMESPACED KIND clusters hmcluster hwameistor.io/v1alpha1 false Cluster events evt hwameistor.io/v1alpha1 false Event localdiskclaims ldc hwameistor.io/v1alpha1 false LocalDiskClaim localdisknodes ldn hwameistor.io/v1alpha1 false LocalDiskNode localdisks ld hwameistor.io/v1alpha1 false LocalDisk localdiskvolumes ldv hwameistor.io/v1alpha1 false LocalDiskVolume localstoragenodes lsn hwameistor.io/v1alpha1 false LocalStorageNode localvolumeconverts lvconvert hwameistor.io/v1alpha1 false LocalVolumeConvert localvolumeexpands lvexpand hwameistor.io/v1alpha1 false LocalVolumeExpand localvolumegroups lvg hwameistor.io/v1alpha1 false LocalVolumeGroup localvolumemigrates lvmigrate hwameistor.io/v1alpha1 false LocalVolumeMigrate localvolumereplicas lvr hwameistor.io/v1alpha1 false LocalVolumeReplica localvolumereplicasnapshotrestores lvrsrestore,lvrsnaprestore hwameistor.io/v1alpha1 false LocalVolumeReplicaSnapshotRestore localvolumereplicasnapshots lvrs hwameistor.io/v1alpha1 false LocalVolumeReplicaSnapshot localvolumes lv hwameistor.io/v1alpha1 false LocalVolume localvolumesnapshotrestores lvsrestore,lvsnaprestore hwameistor.io/v1alpha1 false LocalVolumeSnapshotRestore localvolumesnapshots lvs hwameistor.io/v1alpha1 false LocalVolumeSnapshot resizepolicies hwameistor.io/v1alpha1 false ResizePolicy ``` 详情参见 [CRD 表](../intro/resources.md)。 ## 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`。 ```console $ kubectl get localdisknodes NAME FREECAPACITY TOTALCAPACITY TOTALDISK STATUS AGE k8s-master Ready 28h k8s-node1 Ready 28h k8s-node2 Ready 28h $ kubectl get localdisks NAME NODEMATCH DEVICEPATH PHASE AGE localdisk-2307de2b1c5b5d051058bc1d54b41d5c k8s-node1 /dev/sdb Available 28h localdisk-311191645ea00c62277fe709badc244e k8s-node2 /dev/sdb Available 28h localdisk-37a20db051af3a53a1c4e27f7616369a k8s-master /dev/sdb Available 28h localdisk-b57b108ad2ccc47f4b4fab6f0b9eaeb5 k8s-node2 /dev/sda Bound 28h localdisk-b682686c65667763bda58e391fbb5d20 k8s-master /dev/sda Bound 28h 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。 ```console $ 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 $ kubectl get lsn 10-6-234-41 -o yaml apiVersion: hwameistor.io/v1alpha1 kind: LocalStorageNode metadata: creationTimestamp: "2023-04-11T06:46:52Z" generation: 1 name: 10-6-234-41 resourceVersion: "13575433" uid: 4986f7b8-6fe1-43f1-bdca-e68b6fa53f92 spec: hostname: 10-6-234-41 storageIP: 10.6.234.41 topogoly: region: default zone: default status: pools: LocalStorage_PoolHDD: class: HDD disks: -
