NVMe cache support

Hi, I'v pathed libsynonvme.so.1 . But I found that only nvme ssd on the M2A slot can be recognized. So how can I use the M2Q slot?

My hardware info:

CPU i39100

Motherboard GIGABYTE b365m aorus elite.

SSD WD SN750 1T

I checked the manual of motherboard, it is said that M2Q slot is connected directly to CPU while M2A slot shares bandwidth with SATA3.0 slot

i have a 9900 on a z390 systemboard. It's been a while since I tried m2 in xpenology, but when i tested both slots were working. Heck, I use an NVME on a pcie card now and it works fine.

Your motherboard has some limitations between NVMe and SATA SSD's and some overlap with SATA addressing.  Not sure if any of this applies to your situation.

I'm not sure there is anything to do about it.  The nvme binary is standard Linux accessing the kernel driver and is unaffected by the patch.  I would guess that you would see the same behavior with a real DS918+.

@flyride so it's safe to use them? ... I' ve also tested TWO Samsung 970 EVO (instead of Plus version) and I got the same result in SSH and the same in DSM (they work like a charm) ... but isn't it very strange? Can be the standard Linux binary so firmware version dependant?

Hi all,

 

I am looking to use an NVMe drive as a separate volume (for installing a certain application to) rather than using as a cache.  So far I have installed the drive and verified that it is seen in the BIOS and also confirmed that DSM is not showing it as available for use.  This led me to this thread.

 

I have read most of the pages / posts and understand that the common use of an NVMe is for cache.  I also saw @Hackaro's useful summary on page 6:

 

Quote

The only thing is really working at the moment is a copy of the libsynonvme.so.1 to the right path. So put this file in a public zone of your volume (this is my case) or wherever you like and then with root's privileges (sudo -i) put the lib in the right place: 

 

cp /volume1/public/libsynonvme.so.1 /usr/lib64 cd /usr/lib64 chmod 777  libsynonvme.so.1 shutdown -r now

 

and that's it. The Storage Manager should recognise correctly yours NVMe's and use them as cache. 

 

2 questions if I may:

  1. Should the above process work for me to be able to see the drive in DSM and configure as a new volume?
  2. I am a novice when it comes to linux.  Do I perform the above task using SSH?  Can anyone offer some further guidance (or point to a resource) that lays it out in baby steps for me please?

Thank you guys for you help and support.

No.  This is a limitation of DSM, not the patch. Right now the only "safe" way to do it is to embed DSM as a VM in ESXi, attach the NVMe disk to ESXi and syndicate it as an emulated SATA device to the VM.

Yes, you would need to turn on TELNET and/or SSH capability via a checkbox in Control Panel.  The apps are usually free, such as Putty (on Windows).

 

You do need to learn a little about Linux command line, and there are thousands of Internet resources to help you there.

Hi @flyride

 

Thanks for answering above.  It is a shame that I can't use the NVMe as a separate volume as that was the intended purpose.  I think running VMs for DSM is beyond my technical capability (and sounds risky regarding the volume of data I already have and would not want to lose).  Perhaps I'll take a look at ESXi before completely dismissing it though... in for a penny and all that.

 

I did a little SSH last night actually (just following a guide for something else) so perhaps I can give it a go and at least make use of the NVMe as a cache?

 

Thanks again for helping me out.

Thanks @flyride

Confirmed that it works on DSM 6.2.3-25423. 

Important thing to note here is to Copy the provided "libsynonvme.so.1" file into /usr/lib64 directory.

And if you were using the previous solution of script "libNVMEpatch.sh" , dont forget to remove it from /usr/local/etc/rc.d folder.

 

After you place the file into /usr/lib64 director, the DSM UI will stop working so you have to hard restart the machine.

After reboot, the NVME cache is identified  and shows up in Storage Manager.

 

This is the solution that finally worked for me. (page 4)

Note to self: don't forget to chmod.

 

Huge shout to @The Chief and @flyride for getting us pointing in the right direction to start with.

You have to switch to DS918+ and loader 1.04b and then apply a patch that is found on this forum.

 

There is no DSM internal support for NVMe cache in DS3615xs or DS3617xs.

Just a recap for those who'll want to try NVMe cache because all the thread is quite messy imho. 

 

The above shell script with DSM 6.2.3-25426 Update 2 (on DS918+ , indeed) does not work anymore. At least in my experience it leads in an incorrect state where the two NVMe are not recognised as the same and therefore they cannot be used for a necessary RAID 1 in case of R/W cache. 

 

The only thing is really working at the moment is a copy of the libsynonvme.so.1 to the right path. So put this file in a public zone of your volume (this is my case) or wherever you like and then with root's privileges (sudo -i) put the lib in the right place: 

 




cp /volume1/public/libsynonvme.so.1 /usr/lib64
cd /usr/lib64
chmod 777  libsynonvme.so.1
shutdown -r now

 

and that's it. The Storage Manager should recognise correctly yours NVMe's and use them as cache. 

 

This was quick and easy solution for baremetal (6.2.3-25426 Update 2) using a Crucial P5 M.2 2280 NVMe 1TB SSD. Thank you @Hackaro and thanks to @The Chief @flyride and anyone else that contributed to the great work.

 

Only a few questions. Should we still expect DSM upgrades to wipe this? Should the cache always be removed before upgrades? Can the patch be re-applied on startup by adding the above into a new "libNVMEpatch.sh" and placing into /usr/local/etc/rc.d?

Hi all,, have run into difficulties in getting this running. I installed the patch (details below) and although I still get Juns Loader screen, I can't ping, SSH or web into DSM.

  • Using Jun’s Loader v1.04b and DSM DSM 6.2.2 (can't remember the rest unfortunately)
  • ASRock MB E3C236D2I
  • WD PC SN520 NVMe (128GB)

 

Prior to issue, I had copied "libsynonvme.so.1" to /volume1/backups/

and ran the following commands:

 

sudo -i

cp /volume1/backups/libsynonvme.so.1 /usr/lib64
cd /usr/lib64
chmod 777  libsynonvme.so.1
shutdown -r now

 

Would appreciate any suggestions on how I could get things back to normal. Tried a number of reboots and even removed the MVMe drive. Would anyone know how I could get to the CLI so I could at least try deleting the "libsynonvme.so.1" file?

Just found out about the serial port output. Below is the output. I couldn't get my logins to work at the prompt though :-(

Would really appreciate anyone's feedback on this.

DiskStation login:

 

... success... I created a new USB boot device but couldn't connect.. the serial connection was a godsend!

I had no success with it initially. I noted the 2 NICs I had weren't getting an IP address. They were aggregated on the switch on a VLAN. So to cut out the complexity, I plugged NIC1 into a VLAN port and assigned a static address 192.168.1.100 (using the ifconfig command and a telnet daily password generator, logged in as 'root'). I could finally ping the NAS... so I logged into the Web UI and saw I required an upgrade and to migrate my disks which remained connected. I upgraded using "DSM_DS918+_25426.pat" as recommended and after a while (and a few disk errors to upgrade to an updated file system version), I was back up and running! Hope this is of use to anyone in similar situation. For me, the breakthrough was the serial port which I hadn't been aware of, considering that the live screen doesn't show any log information that I'm aware of.
