Installing on AMD RAID 0 Array SamsungNVMe SSDs - Installer displaying wrong partition and size

Hi everyone,

It’s my first time posting a question on Ask Fedora. And I’d like t ask about the installation of Fedora 34 on a new Asus ROG GX551QS, which came equipped with AMD RAID 0 Array, a pair of Samsung NVMe SSDs for 1TB each.

Here is the partition allocation of the RAID 0 SSDs on Windows:

(See final image, as new members can only embed one image)

In the BIOS setup, here are my RAID array information and here is an information on one of the SSDs (but both are identical except identifier and serial No):

(See final image, as new members can only embed one image)

Once I launched the Live USB of Fedora 34, as usual, you’d choose the drive, and then you’ll handle the partition under custom settings. However, I see all my partitions being merged into just a 930+ GB per SSD partition, and I only have hundreds of MB of free space for Fedora, which isn’t correct:

How do I resolve this such that Fedora can pick up the correct partition information in order for me to allocate that 256GB of un-allocated space created in Windows 10 to Fedora please? Thank you.

Looks like a fake RAID:

You will probably reconsider knowing the level of difficulty and hassle.

Ah, now I understand what the topic is about. Sorry for misinterpreting.
Yes, many modern motherboards offer such a fake raid, or software raids.
They are not 100% compatible to Linux.
Some can’t be seen at all, yours seems to be not entirely recognised.
Maybe it misinterprets the mirrored empty space being a stripe set?

With Linux there can be used true hardware raids or software raids like created with mdadm.

A dual boot configuration with mixed raid technologies on the same disks might be risky. At the end of the day they could try to sync data in different ways, which potentiality could kill SSD by time.

Hi all, I eventually just reinstalled everything and remove RAID altogether (esp. I don’t like how RAID 0 has no fault tolerance), I now use 2 partitions for Windows across two drives, and install Fedora on one of the SSDs. Thanks.
