VM Guest resize on CentOS7 xfs partition

centos7xfs

I must be missing the boat. I'm trying to add more space to a virtual CentOS 7 server XFS partition running inside VMware. I've added 10 GB of space to a drive inside vSphere for the guest. The CentOS 7 server recognizes it cannot seem to get the LVM to recognize it. I'm sure it is something simple I've overlooked but I need another set of eyes to point me in the correct direction. I've followed this, but still not successful.

Thanks guys. Figured it out using a Virtualbox vm so I didn't break anything. Anyhow, the steps were as followed once you added space to your vmware disk through vcenter/vsphere

fdisk /dev/sda - delete and re-add partition and make it an LVM. It's probably good practice to make backups before this step

reboot - had to reboot for the new partition table to be updated

pvresize /dev/sda

lvresize /dev/mapper/cl-root /dev/sda

xfs_growfs / -d

This worked but I was under the impression you could expand xfs partitions in realtime with no reboot
