旅途

如果想飞得高,就该把地平线忘掉

VM-linux中增加一块硬盘

1。增加前先关闭VM,然后编辑VM属性,增加一个vritual disk(scsi),其实是增加一个虚拟磁盘文件。
hard disk2就是我新增加的
 
2。查看目前的磁盘结构
[root@mail ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14         905     7164990   83  Linux
/dev/sda3             906        1032     1020127+  83  Linux
/dev/sda4            1033        1305     2192872+   5  Extended
/dev/sda5            1033        1159     1020096   82  Linux swap / Solaris
/dev/sda6            1160        1305     1172713+  83  Linux
Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table
//说明磁盘/dev/sdb还没有被系统识别
 
3。分区
[root@mail ~]# fdisk /dev/sbd
Command (m for help): //输入m获得帮助信息,n创建分区
Command action
   e   extended
   p   primary partition (1-4)
p //创建主分区
Partition number (1-4): 1 //指定分区的起始柱面
First cylinder (1-130, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-130, default 130):  //设置分区容量,直接回车表示全部
Using default value 130
Command (m for help): t //改变一个分区的系统ID
Selected partition 1
Hex code (type L to list codes): L //查看文件类型对应的Hex
 85  Linux extended //linux  ext3的hex是85
Hex code (type L to list codes): 85
You cannot change a partition into an extended one or vice versa
Delete it first.
Command (m for help): p //列出当前硬盘的分区
Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1         130     1044193+  83  Linux
Command (m for help): //保存
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
4。查看现在的分区
[root@mail ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14         905     7164990   83  Linux
/dev/sda3             906        1032     1020127+  83  Linux
/dev/sda4            1033        1305     2192872+   5  Extended
/dev/sda5            1033        1159     1020096   82  Linux swap / Solaris
/dev/sda6            1160        1305     1172713+  83  Linux
Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1         130     1044193+  83  Linux
5。格式化分区
[root@mail ~]# mkfs.ext3 /dev/sdb1  //格式化成ext3格式
6。挂载分区
[root@mail ~]# mount /dev/sdb1 /tmp
[root@mail ~]# df -h /tmp
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdb1            1004M  1.3M  952M   1% /tmp
 
7。自动挂载
修改/etc/fstab
增加一行
/dev/sdb1               /sdb1                   ext3    defaults        0 0
重起
