I think the only time I've set up the EFI partition on Linux MD RAID during install was for kickstarts, and then Anaconda handled the metadata version and partition type automatically. My desktop has a pair of NVMe drives, using Linux MD RAID, including for the EFI VFAT partition (I set the RAID up manually when I switched from a single drive to a pair). I hadn't thought about it before, but when I've done BIOS updates, I've written out the current settings from within the BIOS (which of course doesn't know Linux MD RAID). Checking now, I see the settings file is on both drives; I guess the BIOS writes to the first drive and then MD RAID syncs it up at next boot (or maybe at the next periodic check)? It'd be nice if Linux could manage the AMD-style motherboard RAID (like the Intel format is handled by the MD RAID system), because I think that would close this write hole too. However, I don't think the format is documented; IIRC AMD had a Linux "driver" for it at one point but didn't keep it up to date. -- Chris Adams <[email protected]> -- _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
