Adding a Virtual Disk to VMWare

If you need to add another virtual disk to an existing Linux VMWare virtual machine (parts of this can be used to add a physical disk to a non-virtual machine too), do the following steps:

First, shutdown your virtual machine, and make a backup of your virtual disk as a safety precaution.

/sbin/shutdown -h now

Next, Add the new virtual disk in Workstation's VM -> Settings menu. Choose IDE for the virtual hardware.

  • Start the VM.
  • Login as root
  • Create a partition table on the new disk using fdisk. This is an interactive tool, so you're going to need to answer a few questions.
    fdisk /dev/hdb
  • choose n for "new partition"
  • choose p for "primary"
  • type 1 for the partition number
  • accept the default start and end options (hit Enter twice)
  • choose w to "write the partition table"

    Make a filesystem on the new partition

    mkfs.ext3 /dev/hdb1

    Mount the filesystem on a temporary location

    mount /dev/hdb1 /mnt

    Copy the partition you wish to move to the new mount (I use /opt in this example)

    cp -rp /opt/* /mnt

    Add a line to /etc/fstab to cause your new partition to be mounted at boot

    echo '/dev/hdb1 /opt  ext3  defaults  1 1' >> /etc/fstab


    /sbin/shutdown -r now

    After rebooting, you can confirm that your disk setup now has the new disk on the /opt directory mount point by typing on the command line:

    df -h

    You should see something like

    # This file is edited by fstab-sync - see 'man fstab-sync' for details
    LABEL=/                 /                       ext3    defaults        1 1
    LABEL=/boot             /boot                   ext3    defaults        1 2
    none                    /dev/pts                devpts  gid=5,mode=620  0 0
    none                    /dev/shm                tmpfs   defaults        0 0
    LABEL=/home             /home                   ext3    defaults        1 2
    LABEL=/opt              /opt                    ext3    defaults        1 2
    LABEL=/opt/IBM          /opt/IBM                ext3    defaults        1 2
    none                    /proc                   proc    defaults        0 0
    none                    /sys                    sysfs   defaults        0 0
    LABEL=/tmp              /tmp                    ext3    defaults        1 2
    LABEL=/usr              /usr                    ext3    defaults        1 2
    LABEL=/var              /var                    ext3    defaults        1 2
    LABEL=SWAP-hda9         swap                    swap    defaults        0 0
    /dev/hdb1 /opt  ext3  defaults  1 1
    /dev/hdc                /media/cdrom            auto    pamconsole,exec,noauto,managed 0 0
    /dev/fd0                /media/floppy           auto    pamconsole,exec,noauto,managed 0 0

    That's it.
