Motherboard RAID not detected

English Hardware
1

Hello,

I have recently had a motherboard malfunction, and I replaced it with a newer motherboard. My new motherboard is ASUS Prime Z690-a. My older motherboard was also an ASUS.

So, after installing the new motherboard and its drivers in Windows 10 (yes, I am dual booting, which is the main reason I am using fake RAID). I also updated to the latest “Intel Optane Memory and Storage Management”. Under Windows, the Intel RAID management tool automatically detected my old RAID 1 configuration, so I did not have to rebuild my array.

Unfortunately, Linux no longer detects my RAID drive, and instead shows the individual drives. The partition on the RAID device used to be found at “/dev/md/Storage_R1_0p1”. I tried the YaST partitioner and GParted, the RAID is not detected. I tried the command “ls /dev/md*”, nothing is found. I also tried the command “sudo mdadm --assemble --scan” nothing is found either.

I am using LEAP 15.4 right now. I tried to boot into a Tumbleweed live USB to see if that helps. The setup does not detect the RAID either, and shows only the individual drives.

Any ideas or suggestions?

Did you research Optane before enabling it? A quick Google search produced nothing but negative, unless possibly for caching, and definitely not when enabled for Windows’ use with RAID.

I am NOT using an Optane setup. However, the RAID function seems to require that the Intel Rapid Storage Technology (Intel RST) feature to be enabled in the BIOS.

Intel/AMD fake BIOS RAID is harmful for Linux.
Use Linux software RAID with Linux.
RAID is not needed for dual boot.

I am not sure why fake RAID would be harmful for Linux. I have used it for over 5 years and never had an issue (until now).

I use fake RAID because I want to share the same data with both Windows and Linux. I use an NTFS filesystem since it is compatible with both. Is there a better solution to share data between Windows and Linux?

With software RAID you would get no such troubles.
I cannot understand connection between RAID and data sharing.

As far as I know, the software RAID implementations in Linux and Windows are not compatible. So, if I create the RAID inside Linux, Windows will not see it when I reboot into Windows, and vice-versa. Am I missing something here?

I would also prefer to not copy over my data to create a new RAID configuration. However, if a software RAID solution will work I will consider it.
