I have a CentOS 7 server that I am testing with. I have 2 volume groups, ol and db. The ol is for the operating system and the db is for databases. I am trying to figure out how I can start with a 5GB /dev/sdb and then in VMware increase it by 10GB and add the extra 10GB to the db volume group. I started with the 5GB and created the logical volumes db01 and db02. Then in vCenter increased the disk from 5GB to 15GB. Do I create a partition? Then if I need to increase again to keep creating partitions?

I can't figure out what I need to do to get that 10GB available to use.
With a Windows server, granted it is GUI based, I can increase the space and then rescan the disk and expand that drive. I figured there has to be a way to do something similar with Linux, no GUI, as Linux usually has 10x as many ways to do something than Windows.
Main goal is to have a method to increase the disk in vCenter and then take the newly created space and increase the volume group.
