Scenario: Create partition and Volume Group 60GB size from 100GB disk on new disk using Parted on CentOS
System: CentOS/RHEL 6 or 7

Steps:
Show new disk:
# fdisk -l | grep sd

[root@server ~]# fdisk -l | grep sd
Disk /dev/sda: 64.4 GB, 64424509440 bytes, 125829120 sectors

/dev/sda2 2099200 81797119 39848960 8e Linux LVM
Disk /dev/sdb: 107.4 GB, 107374182400 bytes, 209715200 sectors
[root@server ~]#

We found new disk is /dev/sdb with total size 100GB

Create new Partition /dev/sdb1 in /dev/sdb using parted.
# parted /dev/sdb

[root@server ~]# parted /dev/sdb

Found the new partition is /dev/sdb1

Create new Volume Group from new partition /dev/sdb1.

[root@server ~]# pvcreate /dev/sdb1
 Physical volume "/dev/sdb1" successfully created.
[root@server ~]# vgcreate VolNFS /dev/sdb1

[root@server ~]#

Create new 60GB size Logical Volume from VolNFS with name lv_nfs then format as xfs

[root@server ~]# lvcreate -L +60G -n lv_nfs VolNFS
 Logical volume "lv_nfs" created.
[root@server ~]# lvdisplay | grep nfs

Create directory then mount the new LV then mount permanently in fstab.

[root@server ~]# mkdir /NFSdisk
[root@server ~]# mount /dev/VolNFS/lv_nfs /NFSdisk/
[root@server ~]# vi /etc/fstab
#New disk
/dev/VolNFS/lv_nfs xfs defaults 0 1

Check new partition type df -h and found successfully mounted on /NFSdisk

[root@server ~]# df -h
