ESXi 手动删除磁区

ESXi 手动删除磁区

某些时候你将磁碟加入成为DataStore时，可能会出现错误：

A specified parameter was not correct.
vm.Host.DiskPartitionInfo.spec
...
...

意指你加入的磁碟可能已经有其他分割无法进行删除成为DataStore，会有这状况可能是ESXi使用fdisk指令来管理磁碟，在你的分割是GPT或是fdisk本身无法管理的都会出现类似的错误，所以你必需要使用其他指令进行手动删除。

partedUtil

使用ssh登入ESXi Server时，执行partedUtil不加参数会出现指令的使用方法：

Usage:
 Get Partitions : get <diskName>
 Set Partitions : set <diskName> ["partNum startSector endSector type attr"]*
 Delete Partition : delete <diskName> <partNum>
 Resize Partition : resize <diskName> <partNum> <start> <end>
 Get Partitions : getptbl <diskName>
 Set Partitions : setptbl <diskName> <label> ["partNum startSector endSector type/guid attr"]*
 Fix Partition Table : fix <diskName>
 Create New Label (all existing data will be lost): mklabel <diskName> <label>
 Show commonly used partition type guids : showGuids
 Get usable first and last sectors : getUsableSectors <diskName>
 Fix GPT Table interactively : fixGpt <diskName>

稍后会使用Delete Partition : delete <diskName> <partNum>进行删除。

寻找磁区

删除磁区前首先寻找该磁区的磁碟名称：

ls -l /vmfs/devices/disks

所以与磁碟、磁区有关的都会在disks这目录内，使用ls -l列出很多资讯

以t10.开头的主要是你机器上的磁碟，以例子中要找的是EZLINK T34这个256GB SSD，它先前在windows使用过，所以要进行手动删除才能成为DataStore，重新执行指令将所有EZLINK T34的都列出来：

ls -l /vmfs/devices/disks/t10.ATA_____EZLINK_T34_256GB*

列出相关的：

-rw-------    1 root     root     256060514304 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________
-rw-------    1 root     root     367001600 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:1
-rw-------    1 root     root     255158087168 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:2
-rw-------    1 root     root     532676608 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:3
/dev/disks # ls -l t10.ATA_____EZLINK_T34*

其他名称后面以:冒号与数字组合的名称为磁区，以这个列表看来总共分割成3个磁区，现在要一一的将三个磁区删除。

删除磁区

承上已经列出要删除磁碟资讯：

t10.ATA_____EZLINK_T34_256GB________________________201410300108________
-rw-------    1 root     root     367001600 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:1
-rw-------    1 root     root     255158087168 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:2
-rw-------    1 root     root     532676608 May 16 15:16 t10.ATA_____EZLINK_T34_256GB________________________201410300108________:3

此时利用partedUtil的Delete Partition : delete <diskName> <partNum>进行删除：

cd /vmfs/devices/disks


partedUtil delete "t10.ATA_____EZLINK_T34_256GB________________________201410300108________" 3

partedUtil delete "t10.ATA_____EZLINK_T34_256GB________________________201410300108________" 2

partedUtil delete "t10.ATA_____EZLINK_T34_256GB________________________201410300108________" 1

以上执行正确后，重新再查看一下时，应该会看到只剩磁碟名称：

ls -l /vmfs/devices/disks/t10.ATA_____EZLINK_T34_256GB*

结果：

-rw-------    1 root     root     256060514304 May 16 16:04 /vmfs/devices/disks/t10.ATA_____EZLINK_T34_256GB________________________201410300108________

确定删除后就可以利用vSphere Client进行重新加入成为DataStore的动作。
