Unable to extend disk size of /sysroot

Hello All,
I have installed OCP 4.8 on vcenter with RHCOS version 48.84.202107202156-0.
The /sysroot partition on the default RHCOS ova image is 16G only, which fills up pretty quickly and leaves the nodes in Not Ready state. So i wanted to increase the disk size.
I increased the disk size from vCenter, but when i try to increase it on the OS, it does not take effect. Can anyone please tell what is the issue?
lsblk shows that extended disk size to be 60G
[root@master-1 core]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 60G 0 disk |-sda1 8:1 0 1M 0 part |-sda2 8:2 0 127M 0 part |-sda3 8:3 0 384M 0 part /boot `-sda4 8:4 0 15.5G 0 part /sysroot
Current sysroot size
[root@master-1 core]# df -hT / Filesystem Type Size Used Avail Use% Mounted on /dev/sda4 xfs 16G 9.8G 5.8G 63% /
[root@master-1 core]# sudo xfs_growfs /sysroot/ meta-data=/dev/sda4 isize=512 agcount=20, agsize=208384 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=0 = reflink=1 data = bsize=4096 blocks=4062971, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0
After this also the size does not change
[root@master-1 core]# df -hT / Filesystem Type Size Used Avail Use% Mounted on /dev/sda4 xfs 16G 9.8G 5.8G 63% /
Tried to run the command on the FS name as well
[root@master-1 core]# sudo xfs_growfs /dev/sda4 meta-data=/dev/sda4 isize=512 agcount=20, agsize=208384 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=0 = reflink=1 data = bsize=4096 blocks=4062971, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0
