RAID provides redundancy while the system is running
RAID provides redundancy for devices - no matter if something is running
RAID alone does not provide boot redundancy.
If a drive fails, the system will continue to run until shutdown. But it
won't boot if the boot area was only set up on the failed disk
what's the point of such nonsense-comments?
yes, when i am an idiot an don't run grub2-install on all disks it#s no
there - but as saif dozens of times: we all know this and it has to be
only done ONCE per drive
after that RAID ensures (ensured before UEFI) that /boot and everything
in that filesystem is redundant
For boot redundancy, the boot loader must be installed on each disk
so what
So that the system can still boot after whichever drive failed.
"so what" meant "tell me something we didn't know before you where born"
With EFI boot, it means there must be an EFI partition on each disk.
But EFI partitions do not need to be identical as long as any of them
can boot the system
so what - the topic is "Transferring an existing system from non-RAID
disks to RAID1 disks in the same computer"
People who install the system on RAID usually expect boot redundancy
and i explained multiple times how to get that with ESP
