由于在装软件,原来的20G空间不够使用,需要扩容操作。

1.关闭虚拟机

2.点击编辑虚拟机设置

选中硬盘,添加,硬盘,推荐,确定大小,完成。

2.启动虚拟机

查看磁盘使用情况:

[root@master ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2        18G  3.0G   14G  18% /
tmpfs           931M   80K  931M   1% /dev/shm
/dev/sda1       291M   39M  238M  14% /boot
/dev/sr0        3.6G  3.6G     0 100% /media/RHEL_6.5 x86_64 Disc 1

对新加的硬盘进行分区,格式化,因为我的磁盘名称是/dev/sdb,所以输入 fdisk /dev/sdb命令:

 [root@master ~]#  fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xc2e1095b.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won‘t be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It‘s strongly recommended to
         switch off the mode (command ‘c‘) and change display units to
         sectors (command ‘u‘).

Command (m for help): m
Command action
   a   toggle a bootable flag
   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition
   l   list known partition types
   m   print this menu
   n   add a new partition
   o   create a new empty DOS partition table
   p   print the partition table
   q   quit without saving changes
   s   create a new empty Sun disklabel
   t   change a partition‘s system id
   u   change display/entry units
   v   verify the partition table
   w   write table to disk and exit
   x   extra functionality (experts only)

Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-652, default 1): 1
Last cylinder, +cylinders or +size{K,M,G} (1-652, default 652):
Using default value 652

Command (m for help): p

Disk /dev/sdb: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 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: 0xc2e1095b

   Device Boot      Start         End      Blocks   Id  System
