Need support on the AMD RAID driver for Linux Ubuntu

Hi,

I've recently put together a Ryzen 1700+ system with X370 chipset and installed dual boot Windows 10 and Ubuntu 16.04 systems (on a NVMe boot drive).   I have configured two RAID sets with RAID 0 and 1 respectively.  They work quite well under Windows, but I cannot get Ubuntu to find the RAID drives.  I did download the driver from the following webpage (Chipset ) and followed the instructions trying to insert the rcraid module to the Linux kernel.  The scripts seem to be successful and I could see that the rcraid.ko did get built and inserted into '/lib/modules/4.10.0-37-generic/kernel/drivers/scsi/' folder and the rest of steps.  However, after restarting, I used 'lsmod' to check, but couldn't find any 'raid' related module being loaded. 

Can anyone help here?

thank you,

TT

Re: Need support on the AMD RAID driver for Linux Ubuntu

Had similar problem, but what I did that wasn't explained in the ISO readme is make the install file executable with "sudo chmod +x install".

Once I rebooted, "sudo fdisk -l" saw the RAID.

Re: Need support on the AMD RAID driver for Linux Ubuntu

* I did ran through the install script (output below)

* I also saw that rcraid.ko got built and copied to "/lib/modules/4.10.0-37-generic/kernel/drivers/scsi/rcraid.ko"

*  There is also load_amdraid script in folder "/usr/share/initramfs-tools/scripts/init-premount/"

I tried to run the load_amdraid script myself, but got this error message:

"insmod: ERROR: could not insert module /lib/modules/4.10.0-37-generic/kernel/drivers/scsi/rcraid.ko: File exists"

Can you or anyone help further?  Thank you in advance!

Re: Need support on the AMD RAID driver for Linux Ubuntu

Haven't seen anybody help here, so I'll add to this. My board is a Gigabyte AX370-Gaming K5. When setting up the EFI, you need to make sure your not running the legacy RAID boot BIOS. you can use it to build the arrays, and boot from Windows, but your Linux system won't see your arrays. Set it to UEFI only. Check your kernel log, "dmesg | grep "rcraid" and look for a line like "rcraid: Array * not allowed by current licence level". If you see that, you know the module loaded, but it won't show disk arrays.

Re: Need support on the AMD RAID driver for Linux Ubuntu

At this point I'm considering buying a REAL array controller with REAL upstream support in the kernel under a normal license.

Re: Need support on the AMD RAID driver for Linux Ubuntu

I have the above mentioned "Array 1 not allowed by current license level" message and I do not know how to deal with it. Please help.

My board is an ASUS prime B350 plus and I am using Kubuntu 17.10. I installed Kubuntu on an external USB drive with the SATA configuration set to RAID, compiled the rcraid.ko and inserted it into the kernel. This all works fine. With help of the install script that is in the AMD package, the kernel module got inserted into the initrd and is automatically loaded at boot. The rcraid.ko module detects my disks. I have access to the CDROM via the rcraid.ko kernel module once it is loaded. However, it does not allow access to the hard drives. Looking into the UEFI BIOS, my current license level is "10". The two WD 2TB disks I have were configured as RAID 1. With Windows they are running fine. I upgraded the AMD RAID BIOS to version 8.1.0-00064. The rcraid kernel module is version 8.1.0-00039. Can this be an issue? The windows driver I was using during Windows install has a version 8.1.0-00026, and this worked fine. Here is the output when inserting the kernel module:

Sometimes I wish AMD forums had a way to escalate things and file JIRA tickets to their devs.

Re: Need support on the AMD RAID driver for Linux Ubuntu

I looked into your boards UEFI menu's, go under the "Boot" tab, look under "Boot Configuration". Look for anything you can change that involves legacy boot, to "UEFI only". Also, under the Boot tab is "CSM" or Compatibility Support Module, try turning this on and off. If your Graphics card doesn't support UEFI, your board will keep toggling this on so it can boot.  You'll know you have "pure" UEFI when you stop seeing option ROM's related to disk controllers and ethernet devices after the first POST screen. Also, look under the "Advanced" tab, in "SATA Configuration" (or under the Advanced tab, can't tell) you should see an option to configure "AMD RAIDXpert2", once you see this, your OS should be able to mount the array as a regular "/dev/sd*" for each array.

Another big thing, if your on any Kernel past the 4.10 branch, the driver module won't compile correctly.  Considering the fact that this software RAID wasn't developed by AMD, but an outside firm that's already been aquired twice by other companies since they made the contract with AMD, I hold little hope this get's fixed quickly.

Re: Need support on the AMD RAID driver for Linux Ubuntu

Honestly, I think AMD should just hand the needed information over to the kernel and dmraid/kpartx people to add support. I managed to get rcraid.ko built thanks to the hint provided on this thread. However NVMe RAID doesn't work and even then SATA RAID isn't working how I expected it to (it manifested itself as /dev/sda with my boot SATA SSD pushed down to /dev/sdb, and the controller and disk isn't showing up in /dev/mapper. On the plus side tho, at least Clonezilla supports imaging this configuration).

Why do they have to make things so complicated.

Re: Need support on the AMD RAID driver for Linux Ubuntu

Because, Like I hinted in that thread​, AMD doesn't own the software we're having problems with. Honestly, AMD has really only been interested in the CPU portion of their platform.  It was only after Buying ATi, and inheriting their chipset tech that AMD was able to make a complete platform on their own (the 700 series) and have been making only slight revisions for the 800 and 900 series. It was really only with the introduction of APU's in 2011 that AMD had to actually put effort into creating a chipset it can call it's own.  Honestly, I love what AMD has done with the graphics side of ATi, putting in the effort to jump through the legal hoops to get as much technical info as possible out to the community to open source, but when you don't own what your selling, you play by their rules.
