I noticed that there was a grub2 update.
From prior experience I know that one needs to manually run
grub2-install to actually update the bootloader. Additionally I run
mdraid, so I need the bootloader on both /dev/sda and /dev/sdb.
[root@jack ~]# grub2-install /dev/sda
Installing for x86_64-efi platform.
grub2-install: error: This utility should not be used for EFI
platforms because it does not support UEFI Secure Boot. If you really
wish to proceed, invoke the --force option.
Make sure Secure Boot is disabled before proceeding.
If you have an EFI system, you normally don't do anything.
Is the EFI partition part of the RAID?
Yes, /boot/efi is a RAID partition.
/dev/md123 on /boot/efi type vfat
(rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=winnt,errors=remount-ro)
Which is /dev/sda4 and /dev/sdb4
Both the bootloader and /boot/efi is raided across two disks, so if one
fails the other one can still be used to boot. This actually happened on
another system with me, last year. I just popped out the failed HD,
popped in another one, booted off the functional drive, and reassembled
all the raid partitions.
Then there's nothing you need to do. grub has been updated.
But what do you mean by the "bootloader" though?
