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.
This script creates the RAID and storage pool on your NVMe drive(s) so you can then create the volume in the Storage Manager.
All you have to do is run the script and type yes and 1, 2, 3 or 4 to answer some simple questions. Then go to Storage Manager and select 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 (except for RAID 1 and Basic).
Supports DSM 7 and later
For DSM 6 use v1 and run without the auto update option.
NEW in v2
- Now shows "M.2 Drive #" the same as storage manager.
- Now uses synostgpool command which allows the following: (Thanks to Severe_Pea_2128 on reddit)
- Now supports JBOD, SHR, SHR2 and RAID F1.
- Added choice of multi-volume or single-volume storage pool. Multi-volume allows overprovisioning.
- Added option to skip drive check.
- No longer need to reboot after running the script.
- No longer need to do an online assemble.
- Removed drive check progress as it was not possible with synostgpool.
- You can see the drive check progress in Storage Manager.
- Removed dry run mode as it was not possible with synostgpool.
- Removed support for SATA M.2 drives.
- If you have SATA M.2 drives use v1 and run without the auto update option.
| RAID Level | Min Drives Required | Maximum Drives | Script version |
|---|---|---|---|
| SHR 1 | 1 or more drives | Unlimited | v2 and later (DSM 7 only) |
| SHR 2 | 4 or more drives | Unlimited | v2 and later (DSM 7 only) |
| Basic | 1 drive | 1 drive | all |
| JBOD | 1 or more drives | Unlimited | v2 and later (DSM 7 only) |
| RAID 0 | 2 or more drives | Unlimited | all |
| RAID 1 | 2 or more drives | 4 drives | all |
| RAID 5 | 3 or more drives | Unlimited | all |
| RAID 6 | 4 or more drives | Unlimited | v1.3.15 and later |
| RAID 10 | 4 or more drives | Unlimited | v1.3.15 and later |
| RAID F1 | 3 or more drives | Unlimited | v2 and later (DSM 7 only) |
If RAID F1 is selected the script enables RAID F1 on Synology models that don't officially support RAID F1.

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.
- Download the latest version Source code (zip) from https://github.com/007revad/Synology_M2_volume/releases
- Save the download zip file to a folder on the Synology.
- Unzip the zip file.
How to enable SSH and login to DSM via SSH
sudo -s /volume1/scripts/syno_create_m2_volume.shNote: Replace /volume1/scripts/ with the path to where the script is located.
If the script won't run check the following:
- 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" - Make sure you unpacked the zip or rar file that you downloaded and are trying to run the syno_create_m2_volume.sh file.
- 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- Create the volume as you normally would:
- Select the new Storage Pool > Create > Create Volume.
- Set the allocated size.
- Optionally enter a volume description. Be creative :)
- Click Next.
- Select the file system (Btrfs or ext4) and click Next.
- 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.
- 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
- Repair degraded storage pool in DSM 7.2 or later
- Upgrade to larger NVMe drives in DSM 7.2 or later
- Repair via SSH for DSM 6
