How to use lvm-resize2fs in super block while?
Check the physical volume for free space, extend the logical volume with the free space. Finally perform an online resize to resize the logical volume, then check the available space. In Centos 7 default filesystem is xfs. xfs file system support only extend not reduce. So if you want to resize the filesystem use xfs_growfs rather than resize2fs.

Why does resize2fs fail in CentOS 7?
Apparently CentOS 7 uses XFS as the default file system and as a result resize2fs will fail.

Please confirm the file system of your instance using below command.

I am getting superblock error when running resize2fs on the new disk.
