仮想マシンのHDDの増設方法†

VMware Playerで、仮想マシンのHDDを増設する方法のメモ ※ゲストOSが ubunntu の場合

パーティションの作成†

$ sudo fdisk /dev/sdb

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x49de55dd.

コマンド (m でヘルプ): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): p
パーティション番号 (1-4, default 1): 1
First sector (2048-41943039, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-41943039, default 41943039):

Created a new partition 1 of type 'Linux' and of size 20 GiB.

コマンド (m でヘルプ): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
