[How to have DS3622xs recognize nvme SSD cache drive (Maybe works on other models).]

Thanks ryancc

 

I have done mine with 2 nvme pcie.

 

 udevadm info /dev/nvme0n1
P: /devices/pci0000:00/0000:00:01.0/0000:01:00.0/nvme/nvme0/nvme0n1

 udevadm info /dev/nvme1n1
P: /devices/pci0000:00/0000:00:01.1/0000:02:00.0/nvme/nvme1/nvme1n1

 

Edited  /etc.defaults/.extensionPorts and add my two pci1

pci1="0000:00:01.0"
pci1="0000:00:01.1"

 

Thanks all for your good job.

Nice! Good to hear that both of yours are working.

[How to have DS3622xs recognize nvme SSD cache drive (Maybe works on other models).]

So I migrated my xpenology server from DS918+ model to DS3622xs, and the nvme cache no longer works since the model number no longer exist in libsynonvme.so.1. I dig into the libsynonvme.so.1 and found it might check your pcie location to have the nvme drive works properly. After inspect the file, I found it just checks /etc.defaults/.extensionPorts and we just need to modify that.

 

Here are the steps:

1. Check your nvme pci location(in my case it's 0000:00:01.0😞

udevadm info /dev/nvme0n1

P: /devices/pci0000:00/0000:00:01.0/0000:01:00.0/nvme/nvme0/nvme0n1

 

2. Modify /etc.defaults/.extensionPorts to have the port number match your nvme location.

cat /etc.defaults/extensionPorts

[pci]

pci1="0000:00:01.0"

3. I did not even restart and the nvme cache drive already appears.  Hope this helps anyone who is looking to solve this.

 

 

Update:

 

If you worry a system update will revert this modification, just add a startup script with root:

sed -i 's/03.2/[your_pci_last_three_digs]/g' /etc.defaults/extensionPorts

 

In this way, no matter what version you goes, this will always stay.

I’ll try this when I upgrade to 3622 tonight. I have a spare nvme and card

Thanks, I have an onboard nvme slot and I could see the drive from cmd but not in GUI.

Will 3622 support nvme cache? I did not see the model under libsynonvme.so.1
