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.

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.

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.
  • 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.
  • Does NOT work for M.2 drives in a M2D20, M2D18, M2D17 or E10M20-T1.

• 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.
  • 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.
  • Works for M.2 drives in a M2D20, M2D18, M2D17 or E10M20-T1.

RAID levels supported	Basic, RAID 0, RAID 1, SHR, JBOD, RAID F1 (see Note)	Basic, RAID 0, RAID 1, RAID 5
Add drive(s) to RAID	Yes, via Storage Manager	No
Change RAID type	Yes, via Storage Manager	No
RAID repair	Yes, via Storage Manager	No
RAID expansion	Yes, via Storage Manager	No

DSM version	DSM 7.2 (and 7.1.1 for some NAS models)	Any DSM version
M.2 drive location	Internal M.2 slots only	Internal M.2 slots, M.2 PCie 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. See Synology_RAID-F1_SHR_switch

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.

1. Package Center > Settings > Package Sources > Add
2. Name: SynoCommunity
3. Location: https://packages.synocommunity.com/
4. Click OK and OK again.
5. Click Community on the left.
6. 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.

1. Run the script then reboot the Synology:

   sudo -i /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
  -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 boot-up

Or you can schedule both Synology_enable_M2_volume 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
