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.

It will work for DSM 7.2 beta 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:

Model	DSM version	Works
DS923+	DSM 7.1.1-42962 Update 4	yes
DS3622xs+	DSM 7.2-64216 Beta	yes
DS3622xs+	DSM 7.1.1-42962 Update 4	yes
RS4021xs+	DSM 7.1.1-42962 Update 2	yes
DS1821+	DSM 7.2-64216 Beta	yes
DS1821+	DSM 7.2-64213 Beta *	yes
DS1821+	DSM 7.1.1-42962 Update 4	?
DS1522+	DSM 7.1.1-42962 Update 4	NO
DS920+	DSM 7.2-64216 Beta	yes
DS920+	DSM 7.1.1-42962 Update 5	NO
DS920+	DSM 7.1.1-42962 Update 4	NO
DS918+	DSM 7.1.1-42962 Update 5	NO

How is this different to the Synology_M2_volume script?

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. And maybe RAID 5 and SHR-2 if you have 4 M.2 drives.
- 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.
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 and RAID 5.
- Works with any DSM version (DSM 6 is still WIP).
- Works with any brand M.2 drives.
- Works with any Synology model that has M.2 slots or can install a PCIe M.2 card.

Feature	Synology_enable_M2_volume	Synology_M2_volume
Ease of use	Easy	Medium
Prompts for answers	No	Yes, multiple times
Online Assemble required	No	Yes
RAID levels supported	Basic, RAID 0, RAID 1, SHR, JBOD, RAID F1 (see Note)	Basic, RAID 0, RAID 1, RAID 5
Non-Synology M.2 drives	Yes	Yes
DSM version	DSM 7.2 beta and 7.1.1, and maybe DSM 7.1 and 7.0	Any DSM version (DSM 6 is WIP)
Synology Models	Maybe only models listed as supported by Synology	Any with M.2 slots or M.2 cards
What it does	Temporarily changes 1 file in DSM	Creates partitons on M.2 drive(s)

Note: RAID F1 requires that RAID F1 is enabled on your Synology model.

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.

Requirements

Because the bc command is not included in DSM you need to install SynoCli misc. Tools from SynoCommunity for this script to work.

Package Center > Settings > Package Sources > Add
Name: SynoCommunity
Location: https://packages.synocommunity.com/
Click OK and OK again.
Click Community on the left.
Install SynoCli misc. Tools

Download the script

See How to download the script for the easiest way to download the script.

How to run the script

Running the script via SSH

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

Run the script then reboot the Synology:

sudo -i /volume1/scripts/syno_enable_m2_volume.sh

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
  -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 -i /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 both Synology_enable_M2_volume and Synology_HDD_db to run when the Synology shuts down, to avoid having to remember to run both scripts after a DSM update.

See How to schedule a script in Synology Task Manager

Screenshots

Here's the result after running the script and rebooting. Note that the stroage 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
