3.2.3. 块卷扩展

在扩展块 PVC 之前，请确保块托管卷有足够大小。

要获得 PVC 的 Heketi 块卷 ID，请在主 OCP 节点上执行以下命令：

oc get pv $(oc get pvc <PVC-NAME> --no-headers -o=custom-columns=:.spec.volumeName) -o=custom-columns=:.metadata.annotations."gluster\.org/volume-id"

# oc get pv $(oc get pvc <PVC-NAME> --no-headers -o=custom-columns=:.spec.volumeName) -o=custom-columns=:.metadata.annotations."gluster\.org/volume-id"

要获得块卷 ID，请执行以下命令：
```
heketi-cli blockvolume info <block-volume-id>
```
```
# heketi-cli blockvolume info <block-volume-id>
```

要获得块托管卷信息，请执行以下命令：
```
heketi-cli volume info <block-hosting-volume-id>
```
```
# heketi-cli volume info <block-hosting-volume-id>
```

注意
确定您有足够的可用大小。

关闭应用容器集。

要通过 heketi-cli 扩展块卷，请执行以下命令：

heketi-cli blockvolume expand <block-volume-id> --new-size=<net-new-size>

# heketi-cli blockvolume expand <block-volume-id> --new-size=<net-new-size>

注意

在展开输出中，确保 Size 和 UsableSize 匹配。当大小和 Usable Size 匹配时，可以执行第 4 到 8 步。

将 PVC-NAME 替换为您的 PVC，并创建一个作业来刷新块卷大小。

要验证 pod 日志的新大小，请执行以下命令：

oc logs refresh-block-size-xxxxx

# oc logs refresh-block-size-xxxxx

Copy to Clipboard

Toggle word wrap

注意

确保 df -Th 输出 post xfs_growfs 反映了新大小：

例如：

oc logs refresh-block-size-jcbzh
df -Th /mnt

# oc logs refresh-block-size-jcbzh
# df -Th /mnt
Filesystem         Type  Size  Used Avail Use% Mounted on
/dev/mapper/mpatha xfs   5.0G   33M  5.0G   1% /mnt

/dev/mapper/mpatha xfs   7.0G   34M  6.0G   1% /mnt

运行以下命令检查作业是否成功：

oc get jobs

# oc get jobs
NAME                 DESIRED   SUCCESSFUL   AGE
refresh-block-size   1         1            36m

要在成功后删除作业，请执行以下命令：

oc delete job refresh-block-size

# oc delete job refresh-block-size
job.batch "refresh-block-size" deleted

Copy to Clipboard

Toggle word wrap

您可以在启动应用程序 pod 后使用新大小。
