一、挂载新盘

新建数据存储

创建新的VMFS数据存储

填写名称

默认下一步

报错如下：

无法创建 VMFS 数据存储 datastore2 - 无法更新 /vmfs/devices/disks/naa.5000c500c05b3276 的磁盘分区。 关闭 

二、解决方式

ESxi 中选择 打开主机“启用 SSH”

然后我们可以直接 远程到主机

列出磁盘命令：

[root@localhost:~] ls -lha /vmfs/devices/disks/ total 21484061513 drwxr-xr-x    2 root     root         512 Jul 12 02:23 . drwxr-xr-x   16 root     root         512 Jul 12 02:23 .. -rw-------    1 root     root        3.6T Jul 12 02:23 naa.5000c500c05b3276 -rw-------    1 root     root       14.6T Jul 12 02:23 naa.5000c500c05b3276:1 -rw-------    1 root     root      930.4G Jul 12 02:23 naa.600508e0000000005357f09dcfa8b606 -rw-------    1 root     root      100.0M Jul 12 02:23 naa.600508e0000000005357f09dcfa8b606:1 -rw-------    1 root     root        4.0G Jul 12 02:23 naa.600508e0000000005357f09dcfa8b606:5 -rw-------    1 root     root        4.0G Jul 12 02:23 naa.600508e0000000005357f09dcfa8b606:6 -rw-------    1 root     root      119.9G Jul 12 02:23 naa.600508e0000000005357f09dcfa8b606:7 -rw-------    1 root     root      802.4G Jul 12 02:23 naa.600508e0000000005357f09dcfa8b606:8 lrwxrwxrwx    1 root     root          20 Jul 12 02:23 vml.02000000005000c500c05b3276535434303030 -> naa.5000c500c05b3276 lrwxrwxrwx    1 root     root          22 Jul 12 02:23 vml.02000000005000c500c05b3276535434303030:1 -> naa.5000c500c05b3276:1 lrwxrwxrwx    1 root     root          36 Jul 12 02:23 vml.0200000000600508e0000000005357f09dcfa8b6064c6f67696361 -> naa.600508e0000000005357f09dcfa8b606 lrwxrwxrwx    1 root     root          38 Jul 12 02:23 vml.0200000000600508e0000000005357f09dcfa8b6064c6f67696361:1 -> naa.600508e0000000005357f09dcfa8b606:1 lrwxrwxrwx    1 root     root          38 Jul 12 02:23 vml.0200000000600508e0000000005357f09dcfa8b6064c6f67696361:5 -> naa.600508e0000000005357f09dcfa8b606:5 lrwxrwxrwx    1 root     root          38 Jul 12 02:23 vml.0200000000600508e0000000005357f09dcfa8b6064c6f67696361:6 -> naa.600508e0000000005357f09dcfa8b606:6 lrwxrwxrwx    1 root     root          38 Jul 12 02:23 vml.0200000000600508e0000000005357f09dcfa8b6064c6f67696361:7 -> naa.600508e0000000005357f09dcfa8b606:7 lrwxrwxrwx    1 root     root          38 Jul 12 02:23 vml.0200000000600508e0000000005357f09dcfa8b6064c6f67696361:8 -> naa.600508e0000000005357f09dcfa8b606:8 

检查磁盘卷是否故障

partedUtil getptbl /vmfs/devices/disks/naa.5000c500c05b3276

输出信心如下：

提示错误：主 GPT 表指出备份 GPT 位于磁盘末尾之外。如果磁盘缩小或分区表损坏，则可能会发生这种情况。通过在最后写入备份表来修复

需要重建分区表

partedUtil setptbl /vmfs/devices/disks/naa.5000c500c05b3276 msdos

然后重新创建新盘完成
