[New: openFATE 314870] add support for booting from a software raid1 partition
Feature added by: Marco Manini (jjletho)

Feature #314870, revision 1
Title: add support for booting from a software raid1 partition

openSUSE Distribution: Unconfirmed
Requester: Important

Requested by: Marco Manini (jjletho)
Partner organization:

Yast installer already supports the creation of software raid (md software raid
i mean) partitions and correctly manages root partition on raid1, lvm or a
combination of both of them, but it does not support at all booting from a
/boot partition which is on a software raid1 volume. It allows you to create a
redundant /boot partition, but it does not manage grub2 correctly. The result
is a system which cannot boot with the first (/dev/sda1) member of the raid
volume in a fail state. yast installs grub2 only on the first raid member.

The feature I propose is to enhance yast installer allowing it to manage /boot
raid1 partition with grub2 so that a system can boot also with raid1 /boot
partition with a failing member

Use Case:
directly from yast installer create a partition layout like this: sda1, sdb1 ->
/dev/md0 -> /boot (ext4) sda2. sdb2 -> /dev/md1 -> swap sda3, sdb3 -> /dev/md2
-> lvm volume group -> / (ext4) sda3, sdb3 -> /dev/md2 -> lvm volume group ->
/home(ext4) and correctly install grub2 so that the system is able to boot also
with a failing raid1 member.
