Partitioning, creating multiple volumes, on multiple HDD in a 4-bay NAS
I currently have 2-bay (DS 216+II) Synology, I purchased a new 4-bay (higher end) and trying to configure my new Synology based on attached image.Is that possible?The key question is how do I create 3 distinct volumes:– Volume 1 (2 mirrored HDD1 and HDD2)– Volume 2 (HDD3 used only for back up)– Volume 3 (HDD4 used only for back up)4-bay system configuration will be different from the 2-bay! (ports, application configuration…. etc..)
First of all you need to
- Open Storage Manager.
- Go to Disk Group and click Create.
- You’ll see available hard drive listed. Create RAID1 with HDD1 and HDD2, then create two “Basic” pool without data protection for HDD3 and HDD4

Follow the steps below to create a volume in the fast creation mode.
- Open Storage Manager.
- Go to Volume and click Create.
- You’ll see the volume creation wizard. Select Quick or Custom depending on your needs. Then follow the steps of the wizard to finish creating the volume.
- Create volume 1 on disk group with RAID1. Volume 2 and Volume 3 from Basic group option.

After successful creation of volumes, you should see them listed under Volume and Storage pools tabs.
