Easily create an M.2 volume on Synology NAS without a lot of typing and no need for any how-to guides. And you don't need Synology branded NVMe drives.

• DSM 7 This script creates the RAID and storage pool on your NVMe drive(s) so you can then create the volume in the DSM GUI.
• DSM 6 This script creates the RAID, storage pool and volume on your NVMe drive(s) for you.

All you have to do is run the script and type yes and 1, 2, 3 or 4 to answer some simple questions. Then reboot, go to Storage Manager, Online Assemble and Create Volume.

It also allows you to create a storage pool/volume spanning internal NVMe drives and NVMe drives in a Synology M.2 PCIe card.

For Xpenology users the script supports an unlimited number of NVMe drives for RAID 0, 5, 6 and 10.

If you later update DSM and your M.2 drives are shown as unsupported and the storage pool is shown as missing, and online assemble fails, you need to run the Synology_HDD_db script. The Synology_HDD_db script should run after every DSM update.

1. Download the latest version Source code (zip) from https://github.com/007revad/Synology_M2_volume/releases
2. Save the download zip file to a folder on the Synology.
3. Unzip the zip file.

How to enable SSH and login to DSM via SSH

sudo -s /volume1/scripts/syno_create_m2_volume.sh

Note: Replace /volume1/scripts/ with the path to where the script is located.

If the script won't run check the following:

1. If the path to the script contains any spaces you need to enclose the path/scriptname in double quotes:

   sudo -s "/volume1/my scripts/syno_create_m2_volume.sh"

2. Make sure you unpacked the zip or rar file that you downloaded and are trying to run the syno_create_m2_volume.sh file.
3. Set the syno_create_m2_volume.sh file as executable:

   sudo chmod +x "/volume1/scripts/syno_create_m2_volume.sh"

  -a, --all        List all M.2 drives even if detected as active
  -s, --steps      Show the steps to do after running this script
  -h, --help       Show this help message
  -v, --version    Show the script version

It also has a dry run mode so you can see what it would have done had you run it for real.

DSM 7

1. Restart the Synology NAS.
2. Go to Storage Manager and select Online Assemble:
   • Storage Pool > Available Pool > Online Assemble
3. Create the volume as you normally would:
   • Select the new Storage Pool > Create > Create Volume.
   • Set the allocated size.

   • Optionally enable Encrypt this volume and click Next.
     • Create an encryption password or enter your existing encryption password.
   • Confirm your settings and click Apply to finish creating your M.2 volume.
4. Optionally enable and schedule TRIM:
   • Storage Pool > ... > Settings > SSD TRIM
   • Note: DSM 7.1.1. has no SSD TRIM setting for M.2 storage pools
   • Note: DSM 7.2 Beta has no SSD TRIM setting for M.2 RAID 0 or RAID 5
