Cannot install on Intel RST RAID 1 array

[alex-maks]

Describe the bug
Trying to install Fedora Silverblue 41 on RAID 1 array assembled through Intel RST. I have two SSDs in my setup. The array is empty initially.

I get an error during the phase "Performing post-installation setup tasks". The error says that anaconda raised UnknownDeviceError Python exception. I also tried with Kinoite and encountered the same error.

As it seems, partitions are created successfully and some files are created. However, I am unable to boot the system.

Meanwhile, Fedora Workstation 41 installs without any problems.

To Reproduce
Install Fedora Silverblue on RAID 1 array assembled through Intel RST.

Expected behavior
Successful installation.

OS version
I am using image Fedora-Silverblue-ostree-x86_64-41-1.4.iso.

Is this hardware RAID or a mix or weird thing? I found:

• https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/rst-linux-paper.pdf
• https://help.ubuntu.com/rst/

We would need the bottom of the error message here and ideally all the installation logs. This is also likely an Anaconda issue so it should be reported there: https://github.com/rhinstaller/anaconda

I also found https://www.reddit.com/r/linuxquestions/comments/no4m0f/is_there_any_linux_distros_that_can_use_intel_rst/ which basically suggests not using it at all.
