ESXi 手動刪除磁區

ESXi 手動刪除磁區

某些時候你將磁碟加入成為DataStore時，可能會出現錯誤：

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

意指你加入的磁碟可能已經有其他分割無法進行刪除成為DataStore，會有這狀況可能是ESXi使用fdisk指令來管理磁碟，在你的分割是GPT或是fdisk本身無法管理的都會出現類似的錯誤，所以你必需要使用其他指令進行手動刪除。

partedUtil

使用ssh登入ESXi Server時，執行partedUtil不加參數會出現指令的使用方法：

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>

稍後會使用Delete Partition : delete <diskName> <partNum>進行刪除。

尋找磁區

刪除磁區前首先尋找該磁區的磁碟名稱：

ls -l /vmfs/devices/disks

所以與磁碟、磁區有關的都會在disks這目錄內，使用ls -l列出很多資訊

以t10.開頭的主要是你機器上的磁碟，以例子中要找的是EZLINK T34這個256GB SSD，它先前在windows使用過，所以要進行手動刪除才能成為DataStore，重新執行指令將所有EZLINK T34的都列出來：

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

列出相關的：

-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*

其他名稱後面以:冒號與數字組合的名稱為磁區，以這個列表看來總共分割成3個磁區，現在要一一的將三個磁區刪除。

刪除磁區

承上已經列出要刪除磁碟資訊：

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

此時利用partedUtil的Delete Partition : delete <diskName> <partNum>進行刪除：

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

以上執行正確後，重新再查看一下時，應該會看到只剩磁碟名稱：

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

結果：

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

確定刪除後就可以利用vSphere Client進行重新加入成為DataStore的動作。
