How to add expand increase disk space on Linux Virtual Machine VM VMware

Steps to add disk space on Linux Virtual Machine.

1. Use fdisk -l command find disk size and Disk NAME:/dev/sda
2. Run df -Th command, identify the partition you want to increase, as well as file system type.
3. Add space on VM, reboot. or shutdown VM, add space.
4. run fdisk -l, verify disk size changed accordingly.
5. fdisk DISK NAME (come from step #1)
6. p, to print the partition table
7. n–new partition, — p, create a primary partition
8. 3, for the partition number. (if you already have 3 partitions, then here you type 4)
9. Hit enter 2 times to accept the default value. verity disk size matches you just added.
10.t, change partition ID.press 3 to select the newly created partition.
11.8e, to change to Linux LVM.
12.w, write changes to the partition table. reboot.
13.run fdisk -l, verify changes has been saved to partition table, as well as 8e type.
write down new partition name: /dev/sda3
14.convert new partition to physical volume
#pvcreate /dev/sda3
15.use below command to determine Volume Group Name to extend.
vgdisplay —- find Volume Group name: rhel
16.use below command to extend physical volume
vgextend rhel /dev/sda3
17.use below command to confirm physical disk space available
vgdisplay rhel
18.use below command to find out Logical Volume Path you want to extend.
lvdisplay —/dev/rhel/root
19.use below command to extend Logical Volume
lvextend -L+#G LV_PATH — lvextend -L+20G /dev/rhel/root
20.expand file type (find out by step #2)

a. for non-RedHat Linux VM.
resize2fs LV PATH —- resize2fs /dev/rhel/root
b. RedHat, CentOS 7 using xfs file type
xfs_growfs LV PATH —- xfs_growfs /dev/rhel/root
c. ext3 file type
ext2online LV PATH — ext2online /dev/rhel/root
