Dell Precision Tower 5820 - FlexBay MiniSAS PCIe NVMe SSD not recognized
-
@hlalex Well we know a few things now.
The only sata controller I see is:
00:17.0 RAID bus controller [0104]: Intel Corporation C600/X79 series chipset SATA RAID Controller [8086:2826]But lsblk doesn’t see any drives in that system. On the host configuration for this system, add the following kernel parameter and reboot back into the debug deploy.
mdraid=trueI have a tutorial on how to configure FOS to see an intel raid configuraiton: https://forums.fogproject.org/topic/7882/capture-deploy-to-target-computers-using-intel-rapid-storage-onboard-raid
I seriously don’t think this will solve your issue because we can’t see any existing disks at the moment.
Since you have fedora working on this system, maybe we can use that to reverse engineer how Fedora make it work.
Boot into fedora and at the linux command prompt key in
sudo lspci -k -nnand post the output here. This will show the pci device with the kernel driver that is controlling it. -
EDIT: This was from a Fedora 27 Live CD.
I think the very last entry is what we are looking for.

@hlalex I think you are spot on with your kernel driver name. The lsblk command from fedora is what I should expect from FOS.
One last thing I should have asked for with fedora, will you provide the output of
sudo uname -aThat will tell us what kernel they are using. -

@hlalex Well after some research, I think I found what is missing. We may need to get the developers involved to recompile the FOS kernel.
First some background.

This framework is designed to provide a generic interface to NVMEM from both the Linux Kernel and the userspace.

@Developers Opinion here? Is there a possibility to get this option turned on for linux kernels 4.15.2 and 4.17.0 for testing purposes?

I just received word from Dell that they are going to swap the FlexBay Carriers out for standard PCIe adapters (similar model to the adapters in the Precision 5810s) that should hopefully work without issues.
I would like to provide as much information as I can before I have to ship them out, so please let me know what other logs/data/tests we may need to work out the issue. I’m sure these drives will become more prevalent in the near future and would like to help as much as I can. Not to mention I have another 40 system lab to refresh next summer, and I would love to have a solution if they wind up with this same drive configuration. -
@hlalex We surely like to get this addressed before you swap out the hardware. I’m sure others will either order the same hardware as you have, or other manufacturers will use this hardware design. It needs to be fixed.
-
@george1421 Agreed. It looks like the replacements will not ship until 8/14 so we have a bit of time for testing.
What baffles me is that I have been in contact with multiple Dell Reps trying to determine exactly which hardware needs to be returned, and none have been able to answer what part is what or point me to any product information for this drive type. As far as I can tell from their site, this particular drive configuration is not currently offered as a retail addition. The specs related to the drive based on the dell support Service Tag lookup lists only:

@hlalex I went ahead and compiled the latest FOS kernel with the suspected missing module enabled. This is kernel version 4.17.13. Understand its not the official FOS kernel because it doesn’t have the customized patches that FOG kernel developers add, but should work for our test to see if we can init that nvme memory device.
I’ll IM you a link to the test kernel.
For this test download the linked kernel to /var/www/html/fog/service/ipxe on the fog server, leave the name as bzImage41713 Then go into the host record for one of these test systems and set the “Host Kernel” parameter to bzImage41713. Then finally pxe boot the target system into debug capture task. Run the lspci -nn command and see if we can detect
b3:00.0 Non-Volatile memory controller [0108]: Device [1c5c:1527]If its in the list then run the lsblk command to see if has something we can mount.
-
Good Morning @george1421. I stopped by the office to test the custom kernel (I’m going to pick up breakfast for my wife on my way home so she should be happy ;). No luck. The first attempt to boot gave init error, and I realized it was trying init_32.xz instead of init.xz. After adding init.xz to the "Host Init " parameter in the host record it booted into debug without issue. Bad news is that
b3:00.0 Non-Volatile memory controller [0108]: Device [1c5c:1527]does not show up with
lspci -nnand only /dev/sdb (pxe boot usb) shows up withlsblk. -
@hlalex Well, digging a bit deeper into this…
Going line by line…
FC27 I see that the disk controller is in SATA mode
00:17.0 SATA controller [0106]: Intel Corporation 200 Series PCH SATA controller [AHCI mode] [8086:a282] Subsystem: Dell Device [1028:0738] Kernel driver in use: ahciFOS the disk controllers was in Raid-on mode
00:17.0 RAID bus controller [0104]: Intel Corporation C600/X79 series chipset SATA RAID Controller [8086:2826]Note that the hardware ID changes between the two modes. (not pointing fingers here) But as I said before linux does not see the disks behind raid-on devices in uefi mode. Even if you are in bios mode, please change the value to ahci mode and pull the lspci from FOS. I don’t believe that lspci under FOS supports the -k prompt, but that info would be handy.
I also found another kernel module that was disabled called “Devices/Memory Controller drivers”. After a bit more research I’m going to compile and updated kernel with Memory Controller support enabled.
-
@george1421 I had noticed that as well, and double checked the Raid settings. It had been turned back on at some point (probably while I was going through everything else). I turned it back off and re-did the debug task with the same results.
It appears that the NVMe PCIe drives use an entirely separate controller from SATA drives. Apparently the specific controller/driver varies based on the interface between the MoBo and SSD. FOS can see the M.2 drives when the are connected via a standard PCIe adapter card, however when the same M.2 drive is connected via the FlexBay MiniSAS backplane, FOS no longer recognizes the drive. This holds true regardless of the SATA controller configuration–the drives are visible with both Raid & AHCI modes.
I found a dell support article that gives some good information about the differences between NVMe and AHCI here.
I checked through the FOS kernel, and found NVME Support is enabled in lines 880-890: https://github.com/FOGProject/fos/blob/master/configs/kernelx64.config#L880
# # NVME Support # CONFIG_NVME_CORE=y CONFIG_BLK_DEV_NVME=y CONFIG_NVME_MULTIPATH=y CONFIG_NVME_FABRICS=y CONFIG_NVME_FC=y CONFIG_NVME_TARGET=y CONFIG_NVME_TARGET_LOOP=y CONFIG_NVME_TARGET_FC=y CONFIG_NVME_TARGET_FCLOOP=yWhich explains why the drives are detected when plugged into a PCIe adapter. The MiniSAS connection is a completely different beast–or at least uses a different controller from the standard NVMe drive.
I will run through the debug again (with Raid off in bios) and post the results of
lspci -nn,lsblk,uname -a, and anything else you suggest. I will also do the same thing with the M.2 plugged in through a PCIe adapter so we have comparison data. -
@hlalex I have 2 additional kernels for you to test, but I will only share with you tomorrow since you should have other activities planned for today.
-
@george1421 Ok, I scripted data collection and pulled fresh info for kernels a, b, c, and F27 Live. I also pulled dmidecode, full lshw ouput, and /proc/diskstats to additional log files. Let me know if they may be of any use I will upload them as well.

@hlalex Very nice. I see somethings in the FC syslog, that are missing in FOS, namely PCI Hotplug and FOS is not initing all of the CPUs, FOS stops at 8. The Developers may need to reconsider an upper limit with these new systems.
That “memory controller” is surely the device we are after.

-
@hlalex There is one more bit of data that would be useful from the FC running image. Collecting the output of
lsmodto get the currently loaded dynamic modules (drivers). FOS doesn’t use dynamic modules, but instead use statically built in modules so lsmod will not work for FOS. But knowing what FC is loading will also feed into the tweaks needed. -

@hlalex Did bzImage version D work any better than the previous ones? I uploaded it last Friday.
-
@hlalex ok I found an interesting driver from your FC
lsmodThe one in question is shpchp which is “SHPC PCI Hotplug driver”, this is a specific hotplug driver (that is not currently enabled in “bzImage41713D”. I’m in the process of recompiling bzImage41713E. Lets see if that one gets us to that nvme drive. When I have version E uploaded I’ll send you an IM. -
@george1421 I must have missed version D, my bad. I will pull it and post the results ASAP.
I will keep an eye out for E as well.
