If have a different opinion on this, as I think it's 100x better to learn sql and just write it directly instead of using the dozens of leaky abstraction of some framework.

Ok, that is assuming /boot is ON the raid which I wouldn't want to rate for probability

But even if it is, you could just pull one after the other and wait for the resilver before pulling the next one (you will hear if it resilvers automatically)

Can't I just extract the key from uefi/tmp in this case? Not that it's easy, but with the right tools you can so it offline with all the time in the world

Why wouldn't this work with Raid5? One of my raid5 hdds cought fire and the server was still running. Talking about mdadm in this case.

5 minutes is plenty to boot initrd from a vm... what's that gonna take? 10 seconds?

Which server today doesnt have Raid? Just pull one hdd out, extract what you need or change the image.

Then you turn off the server, and just start a vm with the captured init and capture the key.

Now you can decrypt the server offline with all the time in the world.
