Vmware Workstation增加硬盘空间

Vmware Workstation增加硬盘空间

************

先将虚拟机Power Off，在Virtual Machine Setting对话框里点击左下角的“Add”，选择“Hard Disk”，之后选择“Create a new virtual disk”，分配容量。

[root@centos u01]# df -h

文件系统              容量  已用 可用 已用% 挂载点

/dev/sda1             6.8G  6.8G     0 100% /

tmpfs                 506M     0  506M   0% /dev/shm

①fdisk -l查看是否识别了新硬盘，如果添加的是IDE硬盘，就应该看到hdb，如果是SCSI硬盘，看到的就应该是sdb

[root@centos u01]# fdisk -l

Disk /dev/sda: 8589 MB, 8589934592 bytes

255 heads, 63 sectors/track, 1044 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1         913     7333641   83  Linux

/dev/sda2             914        1044     1052257+  82  Linux swap / Solaris

Disk /dev/sdb: 4294 MB, 4294967296 bytes

255 heads, 63 sectors/track, 522 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

②使用fdisk /dev/sdc，在出现的选项中选择“w”，即将分区表写入硬盘并退出

[root@centos u01]# fdisk /dev/sdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel. 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)

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.

③fdisk -l查看

[root@centos u01]# fdisk -l

Disk /dev/sda: 8589 MB, 8589934592 bytes

255 heads, 63 sectors/track, 1044 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1         913     7333641   83  Linux

/dev/sda2             914        1044     1052257+  82  Linux swap / Solaris

Disk /dev/sdb: 4294 MB, 4294967296 bytes

255 heads, 63 sectors/track, 522 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

[root@centos u01]# df -h

文件系统              容量  已用 可用 已用% 挂载点

/dev/sda1             6.8G  6.8G     0 100% /

tmpfs                 506M     0  506M   0% /dev/shm

④用mkfs命令将其格式化，mkfs /dev/sdc

[root@centos u01]# mkfs /dev/sdb

mke2fs 1.39 (29-May-2006)

/dev/sdb is entire device, not just one partition!

Proceed anyway? (y,n) y

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

524288 inodes, 1048576 blocks

52428 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=1073741824

32 block groups

⑤用mount命令将其挂载，mount -t ext2 /dev/sdb /media

[root@centos u01]# mount -t ext2 /dev/sdb /media

[root@centos u01]# df -h

文件系统              容量  已用 可用 已用% 挂载点

/dev/sda1             6.8G  6.8G     0 100% /

tmpfs                 506M     0  506M   0% /dev/shm

/dev/sdb              4.0G  8.0M  3.8G   1% /media
