    Excellent Post. I looked all over the NET for the above information. sometimes found some pieces and some times just not very clear instructions. Yours was just perfect and it worked on the first try. This is the way Linux should be taught to anyone Linux newbie or not. Thanks !!!!

    Can we mount the new disk at root "/" partition?

    Why would you not use Logical Volume Manager?

    What if the file system fills up? If you used LVM you could grow the file system with no impact to production.

      We can use LVM as well. But in this article I just gave steps for fdisk which is just another method

    Thank you.

    It would be great to describe how to use parted if HDD size more 2 TB. Nowdays, it is a common already.

    Very good article, should not be ext4 instead of xfs in the fstab file?

    Probably after attaching the new disk you should scan it first then only it will get reflected in “fdisk -l” output. But sometimes it depends which Linux version you are using. Also we can see the new disk info using “dmesg” command.

    • Lakshmi Dhandapani says:

      Thanks for the comment. Here I used RHEL 7 in virtual Infra . Hence when I added a new Disk, it was reflected in “fdisk -l” with out scanning.
