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)

First data block=0

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
