In this tutorial I will demonstrate how to add a hard drive to a storage pool in order to expand the storage space available in a Synology NAS, specifically the ds1821+. I only have one storage pool so I will be demonstrating the pool expansion using my storage pool. This tutorial assumes you have empty drive bays on your NAS. The raid type I am using is SHR (Synology Hybrid Raid.), as opposed to RAID 0, RAID 5, etc.
