Expand a Synology Hybrid RAID volume
I own a Synology DS409slim with two 1TB Toshiba and two 500GB Western Digital disks. Configured using SHR (Synology Hybrid RAID), it allows one volume split on those four disks. I bought this NAS because it uses 2.5" disks and because of the SHR feature. I had one 1TB Toshiba in my MacBook but I took it off and planned on putting it in the NAS, replacing one of the 500GB disk. Here’s what happened.
