SUSE Linux硬盘格式化及挂载

*** 作系统版本：SUSE Linux Enterprise Server 12 SP4

1查看服务器的所有硬盘

2检查是否已经格式化

3格式化硬盘

4新建目录

5挂载目录

6查看硬盘的UUID

7将硬盘对应的UUID配置到fstab文件

8自动挂载验证

9目录验证

UUID是用来唯一标识某个东西的，只要你的磁盘分区没有改变（比如：格式化等等），UUID一般是不会改变的！ 你多次重启一下，并在每次重启之后，记一下UUID，看看它们是不全不同，还是有一次或几次不同！

一、fdisk-l

这个命令会列出当前分区和配置。

[root@cql ~]# fdisk -l

Disk /dev/sda: 215 GB, 21474836480 bytes

255 heads, 63 sectors/track, 2610 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: 0x000e3d27

Device Boot Start End Blocks Id System

/dev/sda1 1 914 7340032 83 Linux

Partition 1 does not end on cylinder boundary

/dev/sda2 914 1437 4194304 82 Linux swap / Solaris

/dev/sda3 1437 2611 9436160 83 Linux

Disk /dev/sdb: 107 GB, 10737418240 bytes

255 heads, 63 sectors/track, 1305 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: 0x00000000

/dev/sdb就是我新添加的硬盘

二、格式化：

[root@cql ~]# mkfs -t ext4 /dev/sdb

mke2fs 14112 (17-May-2010)

文件系统标签=

*** 作系统:Linux

块大小=4096 (log=2)

分块大小=4096 (log=2)

Stride=0 blocks, Stripe width=0 blocks

591008 inodes, 2361547 blocks

118077 blocks (500%) reserved for the super user

第一个数据块=0

Maximum filesystem blocks=2420113408

73 block groups

32768 blocks per group, 32768 fragments per group

8096 inodes per group

Superblock backups stored on blocks:

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

正在写入inode表: 完成

Creating journal (32768 blocks): 完成

Writing superblocks and filesystem accounting information: 完成

This filesystem will be automatically checked every 29 mounts or

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

三、挂载硬盘：

新建文件夹：mkdir /data2

将硬盘挂载到data2下

mount /dev/sdb /data2

四、加入开机自动

我是通过修改/etc/fstab文件，加入开机自动的，反正方法各种各样，都可以的，随自己的心情~

首先查看分区的UUID

[root@cql ~]# blkid

/dev/sda3: UUID="16046051-6a05-4e6b-b5d2-b64258f5e6d2" TYPE="ext4"

/dev/sda1: UUID="1573581f-e2d5-4f7c-a2de-da6e0eb94359" TYPE="ext4"

/dev/sda2: UUID="a0b44529-1476-4cd7-a009-51b879ba163a" TYPE="swap"

/dev/sdb1: UUID="f124b1f5-16df-4d68-bdc4-41aa08562111" TYPE="ext4"

重启，确认结果~

[root@cql ~]# reboot
