Shulou(Shulou.com)11/24 Report--

CTOnews.com November 26, Red Hat Red Hat's engineering team said it was changing BIOS RAID "fake RAID" support for Fedora during the Fedora 38 development cycle. The Fedora installer currently uses DMRAID through the Blivet repository to support BIOS RAID arrays, while Red Hat plans to use MDADM instead.

CTOnews.com learned that this was because DMRAID was no longer actively maintained and the Red Hat Red Hat team wanted to switch to MDADM to reduce a dependency during Fedora installation (currently MDADM is used for software RAID support) and to abandon DMRAID's systemd activation service.

However, switching to MDADM also has its disadvantages. Before RAID disk data format (RAID Disk Data Format) standardization, MDADM did not support all BIOS RAID types. Engineers at Red Hat Red Hat don't know how many people are still relying on old-fashioned BIOS RAID arrays that MDADM doesn't support. The Red Hat team has not yet announced contingency plans or alternatives for Fedora, but would like to hear from users before switching.
