新購買的Linux云服務(wù)器，數(shù)據(jù)盤未做分區(qū)和格式化，無法使用。
可以通過自動格式化和手動格式化兩種方式對Linux云服務(wù)器數(shù)據(jù)盤進行格式化。
注：

（1）格式化后，數(shù)據(jù)盤中的數(shù)據(jù)將被全部清空。請在格式化之前，確保數(shù)據(jù)盤中沒有數(shù)據(jù)或?qū)χ匾獢?shù)據(jù)已進行備份。
（2）為避免服務(wù)發(fā)生異常，格式化前請確保云服務(wù)器已停止對外服務(wù)。

首先檢查是否有數(shù)據(jù)盤：

fdisk -l

[root@VM_77_80_centos ~]# fdisk -l

Disk /dev/vda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000736d7

   Device Boot      Start         End      Blocks   Id  System

Note: sector size is 4096 (not 512)

Disk /dev/vdb: 107.4 GB, 107374182400 bytes
16 heads, 56 sectors/track, 29257 cylinders
Units = cylinders of 896 * 4096 = 3670016 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/vdb1               1       29257   104856864   83  Linux

Disk /dev/vdc: 2147 MB, 2147483648 bytes
16 heads, 63 sectors/track, 4161 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

看到數(shù)據(jù)盤的路徑是/dev/vdb

如果沒有對硬盤進行分區(qū)，請執(zhí)行以下硬盤分區(qū)命令：

fdisk /dev/vdb

依次輸入 n 、p、 1、 回車、回車、wq
這里的VDB是我們上面看到數(shù)據(jù)硬盤的名稱

格式化分區(qū)

mkfs.ext3 /dev/vdb1

[root@VM_77_80_centos ~]#

掛載分區(qū)

mount /dev/vdb1 /www

[root@VM_77_80_centos ~]# mount /dev/vdb1 /www

設(shè)置開機自動掛載分區(qū)

[root@VM_77_80_centos ~]# echo '/dev/vdb1 /www ext3 defaults 0 0' >> /etc/fstab

驗證數(shù)據(jù)盤是否已經(jīng)掛載好了，這里我們已經(jīng)看到/dev/vdb1已經(jīng)掛載上去了。
