resynced all RAID partitions, I ran grub2-install and I'm fairly certain there was a definitive change in grub's behavior, afterwards. Originally three periods were initially shown, for a few seconds, before the grub menu opened. I have a recollection that the number of periods is a diagnostic indications what went wrong if grub fails to start for some reason. This changed to a "Welcome to grub" banner.

So, it looks to me like years of regular grub updates, and countless Fedora releases, did not really end up updating …everything, on a BIOS system.
If I can ask a silly question, given that on UEFI systems grub2-install is redundant, and the initial messages you were getting were indicating you are booting in a UEFI environment, why are you running grub2-install at all?

Because, my experience on my other, bios, system was that grub rpm updates were not updating "everything".

Given that you are indicating that you are booting off a raid environment and hence have Fedora installed on raid, I'm assuming you are using Fedora server, is that correct?

Nope. Workstation.

I'm just curious because I played around with using Raid 10 a couple of years ago and ran into issues where Fedora workstation would not install on raid only Fedora server had support for doing that.

Not sure about the current fedora installer, but the installer that preceded Anaconda had no trouble with creating partitions on two drives and setting them up on raid 1, with mdadm. That's what I have.

One of them is of such vintage is that it went through the experience of grub growing too big for its britches. Years ago grub could no longer fit in the default amount of space before the 1st partition that fedora's installer was using. Existing fedora seats could not be updated to the new release.

No problem. Boot the installer. Assemble the raid. Resize the ext3 filesystem. Make it smaller. Shrink the raid volume. Remove one partition from the raid. Recreatw it on the hd, starting at a higher address. Add it back to the raid volume. Wait for the resync. Repeat with the other hd partition. Now there's more room for the grub bootloader on both hds.

All with stock fedora workstation.

regards,
Steve
