Expand Logical Volume in Red Hat VMware

After adding a separate disk run to verify if the space was added:

  1. fdisk -l2.
  2. create a new partition fdisk /dev/sdb
    1. p – to print current partition table
    2. n – to create a new partition
    3. p – for primary
    4. 1 – depending on the output of the partition table output
    5. press return two times to accept the defaults (first and last sector)
    6. t – to change the system’s partition ID
    7. 8e – to change to Linux LVM
    8. w – to write the changes
  3. restart VM
  4. fdisk -l – to verify that partition was successfully created
  5. convert a partition to physical volume
    $ pvcreate /dev/sdb1
    Physical volume “/dev/sdb1” successfully created
  6. Extend current volume group
    vgextend rhel /dev/sdb1
    Volume group “rhel” successfully extended
  7. Run vgdisplay to verify if free space was added
    vgdisplay rhel | grep “Free”
    Free  PE / Size       4095 / 16.00 GiB
  8. extend logical volume with free space
    lvextend -l +100%FREE /dev/rhel/root
    Extending logical volume root to 66.00 GiB
    Logical volume root successfully resized
  9. Expand ext3 file system online inside of Logical Volume
    xfs_growfs /dev/rhel/root – Red Hat 7
    ext2online /dev/rhel/root
    resize2fs /dev/rhel/root
