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/sdb4Both 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.
