Increase size of PBS Datastore Directory after increasing the size of Disk

Using sgdisk to Extend a Non-LVM Partition:

sgdisk -e /dev/sdb         # Extend the GPT partition to use the entire disk
sgdisk -d 1 /dev/sdb       # Delete the old partition
sgdisk -N 1 /dev/sdb       # Create a new partition to fill the available space
partprobe /dev/sdb         # Notify the system of partition changes
resize2fs /dev/sdb1        # Resize the filesystem to use the new partition size

Ubuntu Machine with LVM

Step 1: Increase/Resize the Disk from the GUI Console

• Use the GUI to increase the disk size of the virtual machine or physical machine.

Step 2: Extend Physical Drive Partition

• Check free space on the disk:

  sudo fdisk -l

• Extend the physical partition:

  growpart /dev/sda 3   # Replace /dev/sda3 with the correct partition

• View physical volumes:

  pvdisplay

• Resize the physical volume to inform LVM that the disk size has changed:

  sudo pvresize /dev/sda3

• Verify the physical volume changes:

  pvdisplay

Step 3: Extend Logical Volume

• View the current logical volumes:

  lvdisplay

• Extend the logical volume to use all available space:

  sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

• Verify the logical volume has been extended:

  lvdisplay

Step 4: Resize the Filesystem

• Resize the filesystem on the logical volume:

  sudo resize2fs /dev/ubuntu-vg/ubuntu-lv

• Verify the changes by listing the disk partitions:

  sudo fdisk -l
