Original GitHub issue: https://github.com/007revad/Synology_M2_volume/issues/75

Hi,

This works with DS3622xs+, DSM 7.2-64570 Update 1. But not when the NVME drive is installed onto an adapter card with the ASM2824 chip. The script sees the drive and formats it but upon reboot, the drive is not available under Online Assemble.

sudo ls -I ram -I loop* -I dm-* /sys/block

md0 nvme0n1 ram10 ram13 ram2 ram5 ram8 synoboot
md1 ram0 ram11 ram14 ram3 ram6 ram9 zram0
md2 ram1 ram12 ram15 ram4 ram7 sda zram1

Can this be made to work with this type of adapter card that does not rely on PCIe bifurcation?

Thanks,

You sent me down a rabbit hole of trying to find out if Synology NAS support PCIe bifurcation, and PLX. And I'm still not sure. I read something about Synology's E10M20-T1 10GbE + 2x M.2 card but I can't remember if was PLX or bifurcation.

I believe your issue is that DSM only looks for Synology's own adaptor cards. But it's interesting that the script can see the NVMe drives that are installed in a non-Synology adaptor card.

I've just finished a script to allow using Synology's M.2 PCIe adaptor cards in Synology NAS that don't officially support those cards. Maybe I can use what I learnt writing that script to enable your non-Synology adaptor card. I just need to figure out how DSM gets the model of PCIe adaptor cards so we can find out what model name DSM sees for your PCIe adaptor card.

After we can determine what model name DSM sees I can try adding it to /usr/syno/etc.defaults/adapter_cards.conf

The Synology E10M20-T1 does not use PLX, so I'd assume the M2D20 and M2D18 don't either.

Someone who owns a Synology SA3400 rackmount NAS said it does not support bifurcation, so I'd assume Synology's RS and DS models would not support bifurcation either.

Apologies,

I shouldn't have stated that the script was working on a DS3622xs+. I am not using Synology hardware so I'll understand if you want to close this issue as unsupported.

I assume you're using Xpenology. It might be better to ask on the Xpenology forums. Though I'd be curious to know what the solution is, if there is one.

Some of these synonvme command options look promising:

Usage: synonvme
--m2-card-model-get <nvme path>                      get m.2 adapter card model
--get-location nvme_path / nvme_name                 get the pcie slot and card slot
--port-type-get nvme_path / nvme_name                get nvme disk port type.
--m2-card-model-get-by-pcie <pcie path>              get m.2 adapter card model by pcie path

What do these commands return?

synonvme --m2-card-model-get /dev/nvme0n1
synonvme --get-location /dev/nvme0n1
synonvme --port-type-get /dev/nvme0n1

Or we can get the with:
udevadm info /dev/nvme0n1

And then use that pcie path with:
synonvme --m2-card-model-get-by-pcie <pcie path>

FX2422N

Very interesting. [FX2422N_sup_nvme] already exists in the DS3622xs+ adaptor_cards.conf in DSM 7.2. The only NAS model listed as supporting the FX2422N is the FS6600N. But we can fix that :)

Run this command (and close Storage Manager if it's open) then open Storage Manager and check if the M.2 card shows up.
sudo set_section_key_value /usr/syno/etc.defaults/adapter_cards.conf [FX2422N_sup_nvme] DS3622xs+

Do you have a link to the M.2 card you bought?

I've found lots of them, in many different brands but I don't know if they all are FX2422N. https://www.google.com/search?q=ASM2824+switch+board

Try adding DS3622xs+ to .usr/syno/etc/adaptor_cards.conf as well
sudo set_section_key_value /usr/syno/etc/adapter_cards.conf FX2422N_sup_nvme DS3622xs+ yes

You might need to reboot before you can see the adaptor card and NVMe drives in DSM.

That's disappointing.

When I googled for FX2422N it found just 1 result, which is a comment on the XPEnology community forum.

That person had a SA6400 and adding SA6400=yes made DSM show their 4 NVMe SSDs on a ASM2824 switch board.
