 ====== Expand Disk on VM ======
+===== VMWare Instruction =====
+**Note:** These steps only apply to EXT3 file systems.
+**Caution:** VMware recommends to take a complete backup of the virtual machine prior to making these changes.
+  * Power off the virtual machine.
+  * Edit the virtual machine settings and extend the virtual disk size. For more information, see [[https://kb.vmware.com/selfservice/search.do?cmd=displayKC&docType=kc&docTypeID=DT_KB_1_1&externalId=1004047|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:
+<code>
+    # fdisk -l
+</code>
+  * Create a new primary partition:
+    * Run the command:
+<code>
+    # fdisk /dev/sda (depending the results of the step 4)
+</code>
+    * 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 on the output of the partition table print.
+    * Press Enter two times.
+    * Press t to change the system's partition ID.
+    * Press 3 to select the newly creation partition.
+    * Type 8e to change the Hex Code of the partition for Linux LVM.
+    * Press w to write the changes to the partition table.
+  * 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 8e type:
+<code>
+    # fdisk -l
+</code>
+  * Run this command to convert the new partition to a physical volume:
+**Note:** The number for the sda can change depending on system setup. Use the sda number that was created in step 5.
+<code>
+    # pvcreate /dev/sda3
+</code>
+  * Run this command to extend the physical volume:
+<code>
+    # vgextend VolGroup /dev/sda3
+</code>
+**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:
+<code>
+    # vgdisplay VolGroup | grep "Free"
+</code>
+  * Run the following command to extend the Logical Volume:
+<code>
+    # lvextend -L+#G /dev/VolGroup00/LogVol00
+</code>
+Where # is the number of Free space in GB available as per the previous command. Use the full number output from Step 10 including any decimals.
+**Note:** To determine which logical volume to extend, use the command lvdisplay.
+  * Or to resize to the number of free extents rather than adding them to the current size in RHEL
+  * To resize to the number of free extents rather than adding them to the current size in RHEL
+<code>
+    # lvextend -l +100%FREE /dev/VolGroup/lv_home
+</code>
+  * Run the following command to expand the ext3 filesystem online, inside of the Logical Volume:
+<code>
+    # resize2fs /dev/VolGroup/lv_home
+</code>
+**Notes:**
+    * Use resize2fs instead of ext2online if it is not a Red Hat virtual machine.
+    * By default, Red Hat and CentOS 7 use the XFS file system you can grow the file system by running the xfs_growfs command.
+  * Run the following command to verify that the / filesystem has the new space available:
+<code>
+    # df -h /
+</code>

 Just powered down the Vm, increased  the disk allocation from vcentre . Power the vm back up. Confirm the kernel is the seeing the increased disk on the existing sda disk .
