Hi. Sorry to beat a dead horse, but I'm really disappointed that those drivers were not ready by release date. Please show your support here for having RAID support in X470 chipset Linux drivers.
When I first booted the 4.16 kernel, it couldn't even find a driver for the RAID controller on my MSI Gaming Plus board.
What makes a good RAID controller?
So, here are my grievances with the current state of affairs:
Is this going to get any proper support, or is the status quo going to continue with Windows getting 1st class treatment while Linux gets the Jim Crow treatment?
I understand you want an official answer and that is why I am telling you this because I would like to see you get that answer. These forums are NOT AMD EMPLOYEES, occasionally you may get an answer from an AMD employee here. There are only 3 i know of that ever answer anything here and I would say it equals less than 1% of the time. The only official way I know of to talk to AMD is to open a support ticket. So take the well written statement you made and apply it to this link to open a ticket: Email Form
I would also add the with Linux the best support typically comes from the support for the each distro itself and those guys typically have the connections with AMD.
I believe the 990FX RAID support is handled by DM-RAID. Quite fiddly to set up tho, but I've done it, although only in Ubuntu. Basically, you need to make sure the raid modules and dm-raid are present in your ramdisk image, and if you intend to use UEFI, make sure kpartx is also installed and available in the ramdisk. Make sure your initialization script runs dm-raid starts first, then kpartx.
Next, your array will show up in /dev/mapper as a device with some weird names instead of as a SCSI or IDE device. in /dev. For example, perhaps as /dev/mapper/promise_DEADBEEF. You can need to point your disk partitioning tool of choice at that and use it like any other SCSI or IDE storage. Partitions will show up at the end of the file as usual, for example if the device is promise_DEADBEEF, first partition will be promise_DEADBEEFA, second will be PROMISE_DEADBEEFB, and so on. You will be able to format and mount those as usual.
In short, you need to retrain yourself to work with /dev/mapper instead of /dev. Also, know that some tools are hardwired to work with /dev/sdx and /dev/hdx (ie Clonezilla) and using them can be an exercise in frustration.
I am also looking for working driver for Linux / Debian.
I want to install system on 2 pcs SSD RAID-1 and boot & work system from this RAID-1.
But I even cannot install - none installator even can see RAID-1 created on the X470.
@miesiu you should use software RAID. Unless you have a hardware RAID
controller (which is actually a software RAID in a SoC package, complete
with its own CPU and RAM), you shouldn't rely on fakeRAID. One day you'll
get a new motherboard with a new fakeRAID schema and your data will be

This should provide you with a working fakeraid driver for Linux. A word of advice- there are some minor quirks regarding power saving (read: power saving is not supported, your mechanical disks will be spinning full speed at all times, although that is good for performance). Also setting up is quite tricky (you need to blacklist the kernel AHCI driver. It’s all or nothing. Also make sure the initrd image has a copy of the driver installed). I have this running on a B450 motherboard with 4 disks and it works great.
