Pvcreate can't open /dev/xvda2 exclusively mounted filesystem

I downloaded the RH Linux 6.7 from RHEL, I wanted to extend the storage for "/" from default 16GB to say 200GB. Here’s the steps I tried is :

1. Init 1
2. Using “fdisk /dev/xvda” , delete the swap /dev/xvda3 as well as /dev/xvda2
3. Re-create /dev/xvda2 with linux LVM using new end blocks
4. save and exit,
5. when I try to perform “pvcreate /dev/xvda2”, as there is a chance to re-extend the storage for /dev/xvda2, it fails with below exception:

Code:

pvcreate can't open /dev/xvda2 exclusively mounted filesystem

please advice the resolution. Your help is appreciated.

VGEXTEND(8)                                                   System Manager's Manual                                                  VGEXTEND(8)

NAME

       vgextend - add physical volumes to a volume group

SYNOPSIS

       vgextend  [-A|--autobackup  y|n]  [-d|--debug]  [-h|-?|--help] [--restoremissing] [-f|--force] [-t|--test] [-v|--verbose] [ PHYSICAL DEVICE
       OPTIONS ] VolumeGroupName PhysicalDevicePath [PhysicalDevicePath...]

DESCRIPTION

       vgextend allows you to add one or more initialized physical volumes ( see pvcreate(8) ) to an existing volume group to extend it  in  size.
       Moreover,  it  allows  you to re-add a physical volume that has gone missing previously, due to a transient device failure, without re-ini-
       tialising it. Use vgextend --restoremissing to that effect.

       If PhysicalDevicePath was not previously configured for LVM with pvcreate (8), the device will be initialized with the same default  values
       used  with  pvcreate.  If non-default pvcreate values are are desired, they may be given on the commandline with the same options as pvcre-
       ate.  See PHYSICAL DEVICE OPTIONS for available options.  Note that the restore-related options such as --restorefile, --uuid, and --physi-
       calvolumesize are not available.  If a restore operation is needed, use pvcreate (8) and vgcfgrestore (8).

OPTIONS

       See lvm for common options.

PHYSICAL DEVICE OPTIONS

       The  following  options  are  available  for initializing physical devices in the volume group.  These options are further described in the
       pvcreate man page.

       -f, --force

       -y, --yes

       -Z, --zero y|n

       --labelsector sector

       --metadatasize size

       [--metadataignorey|n]

       --pvmetadatacopies copies

       --dataalignment alignment

       --dataalignmentoffset alignment_offset

Examples
       "vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume group "vg00"  by  the  new  physical  volumes  (see  pvcreate(8)  )
       "/dev/sdn1" and /dev/sda4".
