Synology enable M2 volume

Description

Enable creating volumes with non-Synology M.2 drives

This script will:

• Enable creating M.2 storage pools and volumes all from within Storage Manager.
• Enable Health Info for non-Synology NVMe drives (not in DSM 7.2.1 or later).

It will work for DSM 7.2 and some models running DSM 7.1.1. As for a full list of which models it will work with, I don't know yet. I do know it does work on models listed by Synology as supported for creating M.2 volumes, and some '21 and newer enterprise models.

Confirmed working on

How is this different to the Synology_M2_volume script?

• Synology_HDD_db:

  • Allows creating an M.2 storage pool and volume all from within Storage Manager with any brand M.2 drive.
  • Works with most '20 series and newer model Synology NAS using DSM 7.2 or later.

• Synology_enable_M2_volume:

  • Allows creating an M.2 storage pool and volume all from within Storage Manager with any brand M.2 drive.
  • Gives you the option of SHR and JBOD, as well as RAID 0, RAID 1 and Basic.
  • Enables Health Info for non-Synology NVMe drives.
  • Add drive(s) and change RAID type work from within Storage Manager.
  • RAID repair and expansion work from within Storage Manager.
  • Easy to run as there a no questions to answer.
  • Works with DSM 7.2 beta and 7.1.1 (may work with DSM 7.1 and 7.0).
  • Works with any brand M.2 drives.
  • May only work with models Synology listed as supporting M.2 volumes.
  • Can be scheduled to run at boot or shut down.
  • Does NOT work for M.2 drives in a M2D20, M2D18, M2D17 or E10M20-T1.
  • Does NOT allow creating a storage pool/volume spanning internal NVMe drives and NVMe drives in a Synology M.2 PCIe card.

• Synology_M2_volume:

  • Creates the synology partitions.
  • Creates the storage pool.
  • Requires you to do an Online Assemble in Storage Manager before you can create your volume.
  • A little more complicated as there are questions that you need to answer.
  • Gives you the option of Basic, RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10.
  • Works with any DSM version.
  • Works with any brand M.2 drives.
  • Works with any Synology model that has M.2 slots or can install a Synology PCIe M.2 card.
  • Works for M.2 drives in a M2D20, M2D18, M2D17 or E10M20-T1.
  • Works for creating a storage pool/volume spanning internal NVMe drives and NVMe drives in a Synology M.2 PCIe card.
  • Can NOT be scheduled to run at boot or shut down.

Note 1: RAID F1 requires a Synology model that supports RAID F1.

Note 2: RAID 5 requires 3 or more NVMe drives. RAID 6 and 10 require 4 or more NVMe drives.

Note 3: Synology_M2_volume requires DSM 7 for SHR, SHR-2, JBOD and RAID F1.

TRIM support:

• DSM 7.2 and later has no SSD TRIM setting for M.2 RAID 0 storage pools.
• DSM 7.1.1. has no SSD TRIM setting for M.2 storage pools.

If you run this script then use Storage Manager to create your M.2 storage pool and volume and then run the script again with the --restore option to restore the original setting your storage pool and volume survive and the annoying notifications and warnings are gone.

Your volume also survives reboots and DSM updates.

Download the script

1. Download the latest version Source code (zip) from https://github.com/007revad/Synology_enable_M2_volume/releases
2. Save the download zip file to a folder on the Synology.
   • Do NOT save the script to a M.2 volume. After a DSM or Storage Manager update the M.2 volume won't be available until after the script has run.
3. Unzip the zip file.

How to run the script

Running the script via SSH

How to enable SSH and login to DSM via SSH

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

1. Run the script then reboot the Synology:

   sudo -s /volume1/scripts/syno_enable_m2_volume.sh

2. Go to Storage Manager and create your M.2 storage pool and volume(s).

Options:

  -c, --check           Check value in file and backup file
  -r, --restore         Restore backup to undo changes
  -n, --noreboot        Don't reboot after script has run
  -e, --email           Disable colored text in output scheduler emails
      --autoupdate=AGE  Auto update script (useful when script is scheduled)
                          AGE is how many days old a release must be before
                          auto-updating. AGE must be a number: 0 or greater
  -h, --help            Show this help message
  -v, --version         Show the script version

Extra Steps:

To get rid of drive database outdated notifications and unrecognised firmware warnings run Synology_HDD_db which will add your drives to DSM's compatibile drive databases, and prevent the drive compatability databases being updated between DSM updates.

sudo -s /path-to-script/syno_hdd_db.sh --noupdate

What about DSM updates?

After any DSM update you will need to run this script, and the Synology_HDD_db script again.

Schedule the script to run at shutdown

Or you can schedule Synology_enable_M2_volume to run when the Synology shuts down and Synology_HDD_db to run when the Synology boots up, to avoid having to remember to run both scripts after a DSM update.

See How to schedule a script in Synology Task Scheduler

Screenshots

Here's the result after running the script and rebooting. Note that the strorage pool is being created in Storage Manager and there's no Online Assembly needed. SHR and JBOD are also available.

After reboot I got some notifications saying the M.2 drives can be managed

No M2 Storage Pool or Volume yet

Non-Synology M.2 drives

Create Storage Pool 2

I wonder if RAID 5 and SHR-2 would be available if I had four M.2 drives.

RAID choices including SHR and JBOD

Select my non-Synology M.2 drives

We have an SHR M.2 storage pool

Create Volume 2

Finished Creating Volume 2
