Associated release criterion
This test case is associated with the Fedora_41_Beta_Release_Criteria#custom-partitioning release criterion. If you are doing release validation testing, a failure of this test case may be a breach of that release criterion. If so, please file a bug and nominate it as blocking the appropriate milestone, using the blocker bug nomination page.


A complete installation using a software RAID device for the root (/) file system. For more details on RAID please consult .


  1. Use a system with multiple disks but no hardware or firmware RAID arrays for testing: a virtual machine with multiple virtual disks is fine

How to test

  1. Boot the installer using any available means
  2. At the Installation Destination screen, select at least two disks, and ensure the Custom option is selected under Storage Configuration, then click Done
  3. Remove existing partitions, if necessary
  4. Create the required boot partitions needed for your architecture as non-RAID partitions. This includes /boot and swap
  5. Create a partition, set its mount point to / and set its type to RAID (stripe (RAID 0) or mirror (RAID 1) are both fine)
  6. Optionally, also create a RAID /home partition
  7. Finish the installation, choosing all provided defaults

Expected Results

  1. The installer should successfully create and install to the RAID devices: unrelated failures should be reported but do not constitute a failure of this test case
  2. After booting the installed system, inspection of /proc/mdstat should confirm that the partitions designated as RAID devices are in fact RAID devices
