阿里云ECS服务器(linux)挂载硬盘

1.查看系统挂载

[root@iZ234wzhfriZ ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/vda1 40G 2.3G 36G 7% /

tmpfs 3.9G 0 3.9G 0% /dev/shm

2.查看磁盘列表(vdb还没有进行分区)

[root@iZ234wzhfriZ ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes

255 heads, 63 sectors/track, 5221 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: 0x00078f9c

Device Boot Start End Blocks Id System

/dev/vda1 * 1 5222 41940992 83 Linux

Disk /dev/vdb: 107.4 GB, 107374182400 bytes

16 heads, 63 sectors/track, 208050 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

3.分区：

fdisk /dev/vdb

[root@iZ234wzhfriZ ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes

255 heads, 63 sectors/track, 5221 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: 0x00078f9c

Device Boot Start End Blocks Id System

/dev/vda1 * 1 5222 41940992 83 Linux

Disk /dev/vdb: 107.4 GB, 107374182400 bytes

16 heads, 63 sectors/track, 208050 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: 0x1ef51bc1

Device Boot Start End Blocks Id System

/dev/vdb1 1 208050 104857168+ 83 Linux

4.格式分区/dev/vdb1：

mkfs.ext4 /dev/vdb1

[root@iZ234wzhfriZ ~]# mkfs.ext4 /dev/vdb1

mke2fs 1.41.12 (17-May-2010)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

Stride=0 blocks, Stripe width=0 blocks

6553600 inodes, 26214292 blocks

1310714 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=4294967296

800 block groups

32768 blocks per group, 32768 fragments per group

8192 inodes per group

Superblock backups stored on blocks:

32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,

4096000, 7962624, 11239424, 20480000, 23887872

Writing inode tables: done

Creating journal (32768 blocks): done

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 31 mounts or

180 days, whichever comes first. Use tune2fs -c or -i to override.

5.挂载：

创建挂载目录

[root@iZ234wzhfriZ /]# mkdir data

mount /dev/vdb1 /data

[root@iZ234wzhfriZ /]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/vda1 40G 2.3G 36G 7% /

tmpfs 3.9G 0 3.9G 0% /dev/shm

/dev/vdb1 99G 188M 94G 1% /data

6.把挂载配置/etc/fstab中重启会自动挂载
