This article describes how to extend a physical disk which is formatted as XFS if LVM is not an option.
As shown below the /dev/sdb device is formatted as xfs and mounted under /test. Currently its capacity is 7GB.
Lets extend the physical volume device by adding 2GB more on it.
However capacity will not be extended on Linux because the physical disk need to be extended also with parted. As you can see the partition number is 1 and it is needed for the next commands.
Execute the below command:
parted -s -a opt /dev/sdb "resizepart 1 100%"
If not unmounted you will get the below warning. Proceed with the umount
umount /dev/sdb
Execute again the command for resizing. You should now have a successful result.
Verify the new capacity:
Mount disk and grow its size
Verify the new capacity on the operating system
