VMware linux系统扩展磁盘

1.关闭虚拟机，编辑虚拟机，点磁盘，扩展，调整磁盘大小

2.启动虚拟机在root登录

 [root@node1 ~]# fdisk -l

 

Disk /dev/sda: 32.2 GB, 32212254720 bytes

255 heads, 63 sectors/track, 3916 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

 #fdisk /dev/sda #用命令进行分区

switch off the mode (command'c') and change display units to sectors (command'u').

First cylinder (1306-4568, default 1306): # 回车，按默认值

The partition table has been altered! Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.

The kernel still uses the old table.

The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8) Syncing disks.

在次查看

[root@node1 ~]# fdisk -l

Disk /dev/sda: 32.2 GB, 32212254720 bytes 255 heads, 63 sectors/track, 3916 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda1 * 1 2355 18916506 83 Linux

/dev/sda2 2356 2610 2048287+ 82 Linux swap / Solaris

/dev/sda3 2611 3916 10490445 83 Linux

这个分区是新添加出来的

   执行格式化命令：mkfs -t ext3 /dev/sda3

 

出现下面的错误

[root@node1 ~]# mkfs -t ext3 /dev/sda3 mke2fs 1.39 (29-May-2006) Could not stat /dev/sda3 --- No such file or directory The device apparently does not exist; did you specify it correctly?

看看是否安装了 parted包

[root@node1 ~]# rpm -q parted parted-1.8.1-29.el5 parted-1.8.1-29.el5 [root@node1 ~]# partprobe #然后执行这个命令在重新执行格式化 Error: Error opening /dev/md0: No such file or directory [root@node1 ~]# mkfs -t ext3 /dev/sda3

执行格式化后要对磁盘挂在

[root@node1 ~]# mkdir /mnt/ndisk   创建一个挂在点

[root@node1 ~]# mount /dev/sda3 /mnt/ndisk  将刚刚格式化好的进行挂在

[root@node1 ~]# vi /etc/fstab   编辑开机启动文件自动挂在 

/dev/sda3    /mnt/ndisk ext3  defaults 1 2

 上面的命令不能添加磁盘到根目录的下面
