Devious

Hi all, I know this is not the right forum or even place to ask about my issue as its not related to XPEnology at all. But all of research have lead me to this place alongside reddit posts that share similar properties, as I dived into this & much of my information/knowledge was obtained from here which helped me out tinkering with my box. That being said here is what I've done so far, hopefully not in vein. As titled,I own a DS1621+ NAS which has native NVME support, & following these guides : - [[Guide] Use NVME SSD as storage volume instead of cache in DS918 : synology] - [How To: Create a usable pool/volume to use as storage using NVMe(s) in the M.2 slots on the DS920+ (and others) running DSM 7 : synology] I was able to have built-in NVME drive configured as volume instead of cache & working flawlessly. I've tried using the same approach with (E10M20-T1) card & it wont work at all, as soon as i create (/dev/mdX) & reboot, it gets deleted. Then I've stumbled upon these : - [NVMe cache support - Page 9 - DSM 6.x - XPEnology Community] - [How to have DS3622xs recognize nvme SSD cache drive (Maybe works on other models). - Developer Discussion Room - XPEnology Community] Based of posts above I've had no success with these methods : Using patch (libNVME.sh) gave me an error (already patched?). Patching (libsynonvme.so.1) was no-go as this file doesn't contain (hard coded PCI addresses) thus rendering above patch useless. Was left with (/etc.defaults/extensionPorts) & (/etc/extensionPorts) & that didn't work even though files were present in my system (presume were created automatically when i installed the card), as i have changed values based of pci addresses I've found (/0000:08:04.0 - nvm0n1) & (/0000:08:08.0 - nvme1n1). Any help would be great if I can use this card, or I'll have to (ebay)-it as return window is closed from amazon & would have to replace it with a supported model from Synology & shift these drives to internal bays. Forgot to mention that I was able to enable the NIC card when I compiled needed driver based of my architecture & running perfectly Here is all my info I could gather: DS1621+ DSM 6.2.4-25556 Upadate 6 NAS:~# udevadm info /dev/nvme0n1 P: /devices/pci0000:00/0000:00:01.2/0000:07:00.0/0000:08:04.0/0000:0c:00.0/nvme/nvme0/nvme0n1 N: nvme0n1 E: DEVNAME=/dev/nvme0n1 E: DEVPATH=/devices/pci0000:00/0000:00:01.2/0000:07:00.0/0000:08:04.0/0000:0c:00.0/nvme/nvme0/nvme0n1 E: DEVTYPE=disk E: ID_PART_TABLE_TYPE=dos E: MAJOR=259 E: MINOR=0 E: PHYSDEVBUS=pci E: PHYSDEVDRIVER=nvme E: PHYSDEVPATH=/devices/pci0000:00/0000:00:01.2/0000:07:00.0/0000:08:04.0/0000:0c:00.0 E: SUBSYSTEM=block E: SYNO_ATTR_SERIAL=XXXXXXXXXXXXX E: SYNO_DEV_DISKPORTTYPE=INVALID E: SYNO_INFO_PLATFORM_NAME=v1000 E: SYNO_KERNEL_VERSION=4.4 E: USEC_INITIALIZED=150484 NAS:~# udevadm info /dev/nvme1n1 P: /devices/pci0000:00/0000:00:01.2/0000:07:00.0/0000:08:08.0/0000:0d:00.0/nvme/nvme1/nvme1n1 N: nvme1n1 E: DEVNAME=/dev/nvme1n1 E: DEVPATH=/devices/pci0000:00/0000:00:01.2/0000:07:00.0/0000:08:08.0/0000:0d:00.0/nvme/nvme1/nvme1n1 E: DEVTYPE=disk E: ID_PART_TABLE_TYPE=dos E: MAJOR=259 E: MINOR=1 E: PHYSDEVBUS=pci E: PHYSDEVDRIVER=nvme E: PHYSDEVPATH=/devices/pci0000:00/0000:00:01.2/0000:07:00.0/0000:08:08.0/0000:0d:00.0 E: SUBSYSTEM=block E: SYNO_ATTR_SERIAL=XXXXXXXXXXXXX E: SYNO_DEV_DISKPORTTYPE=INVALID E: SYNO_INFO_PLATFORM_NAME=v1000 E: SYNO_KERNEL_VERSION=4.4 E: USEC_INITIALIZED=150943 NAS:~# nvme list Node SN Model Namespace Usage Format FW Rev ---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- -------- /dev/nvme0n1 XXXXXXXXXXXXX Samsung SSD 980 PRO 1TB 1 14.14 MB / 1.00 TB 512 B + 0 B 5B2QGXA7 /dev/nvme1n1 XXXXXXXXXXXXX Samsung SSD 980 PRO 1TB 1 253.77 GB / 1.00 TB 512 B + 0 B 5B2QGXA7 /dev/nvme2n1 XXXXXXXXXXXXX SK hynix BC501 HFM256GDJTNG-8310A 1 256.06 GB / 256.06 GB 512 B + 0 B 80002C00 NAS:~# synonvme --is-nvme-ssd /dev/nvme0n1 It is a NVMe SSD NAS:~# synonvme --is-nvme-ssd /dev/nvme1n1 It is a NVMe SSD NAS:~# synonvme --m2-card-model-get /dev/nvme0n1 E10M20-T1 NAS:~# synonvme --m2-card-model-get /dev/nvme1n1 E10M20-T1 NAS:~# synonvme --model-get /dev/nvme0n1 Model name: Samsung SSD 980 PRO 1TB NAS:~# synonvme --model-get /dev/nvme1n1 Model name: Samsung SSD 980 PRO 1TB NAS:~# cat /etc/extensionPorts [pci] pci1="0000:00:01.2" NAS:~# cat /etc.defaults/extensionPorts [pci] pci1="0000:00:01.2" NAS:~# dmesg |grep nvme [ 5.963626] nvme nvme0: pci function 0000:0c:00.0 [ 5.969004] nvme nvme1: pci function 0000:0d:00.0 [ 5.974554] nvme nvme2: pci function 0000:0f:00.0 [ 6.075975] nvme0n1: [ 6.081266] nvme1n1: [ 6.085386] nvme2n1: NAS:~# lspci -tvnnq -[0000:00]-+-00.0 Advanced Micro Devices, Inc.
