Hello

As a new user, it's likely a better idea to consult with your data center or a qualified system administrator to help you with adding the additional hard drive. You risk data loss if you make a mistake. If you do prefer to complete the action on your own, then you may find third-party tutorials such as this one helpful:

Thank you.

i have done mounting of lvm by

mount /dev/VolGroup00/lvm00 /home

will i have to add it in /etc/fstab for mounting ? /dev/VolGroup00/lvm00 /home ext4 default 0 0

Yes, you should add an entry for it in /etc/fstab so it's mounted at boot time.

Thank you.
