Caution: VMware recommends having a complete backup of the virtual machine prior making these changes.
- Power off the virtual machine.
- Edit the virtual machine settings and extend the virtual disk size. For more information, see Increasing the size of a virtual disk (1004047).
- Power on the virtual machine.
- Identify the device name, which is by default /dev/sda, and confirm the new size by running the command:
# fdisk -l -
Create a new primary partition:
- Run the command:
# fdisk /dev/sda (depending the results of the step 4)
- Press p to print the partition table to identify the number of partitions. By default there are 2: sda1 and sda2.
- Press n to create a new primary partition.
- Press p for primary.
- Press 3 for the partition number, depending the output of the partition table print.
- Press Enter two times.
- Press w to write the changes to the partition table.
- Run the command:
- Restart the virtual machine.
- Run this command to verify that the changes were saved to the partition table and that the new partition has an 83 type:
# fdisk -l - Run this command to convert the new partition to a physical volume:
# pvcreate /dev/sda3 - Run this command to extend the physical volume:
# vgextend VolGroup00 /dev/sda3
Note: To determine which volume group to extend, use the command vgdisplay. - Run this command to verify how many physical extents are available to the Volume Group:
# vgdisplay VolGroup00 | grep "Free" - Run the following command to extend the Logical Volume:
# lvextend -L+#G /dev/VolGroup00/LogVol00
Where # is the number of Free space in GB available as per the previous command.
Note: to determine which logical volume to extend, use the command lvdisplay. - Run the following command to expand the ext3 filesystem online, inside of the Logical Volume:
# resize2fs /dev/VolGroup00/LogVol00
Note: Use resize2fs instead of ext2online if it is not a Red Hat virtual machine. - Run the following command to verify that the / filesystem has the new space available:
# df -h /
