Manual Install of CentOS 7 on RAID1 + RAID 10 (UEFI)

[Ruben Di Battista]

Hello everybody,

I've been struggling with this problem for two weeks without figuring it
out.

I need to install CentOs 7 on a UEFI machine manually. The strategy I'm
following is to install first the system on the first hard disk /dev/sda
and then migrate the data to the md arrays. Well, i get "Boot Failed"
and I cannot really figure it out why.


More details:

Or even:
https://www.centos.org/forums/viewtopic.php?f=47&t=56482

Any hints?

It really doesn't say why?

Often it failed to mount / . Probable causes are missing or damaged
initrd or initramfs.

I use a Unix based operating system, which means I get laid almost as often
as I have to reboot my computer.

What do you mean by "migrate the data to the md arrays" ?

No, thanks. It's Usenet here, not the web. Would you point to a Usenet
post in a web forum ?

More specifically : did you touch the EFI system partition in any way ?
You must not.
