greetings again |

yesterday I received a shiny new server for a client. |
4 |
|
5 |
It brings 4 x 1 TB SATA disks, is capable of UEFI and I started setting |
6 |
it up. |
7 |
|
8 |
GPT partitioning, small partition(s) for the ESP, some swap, and bigger |
9 |
partitions of type fd=raid for creating 2 mdadm-raids (rootfs and data) |
10 |
with level 6. |
11 |
|
12 |
ok so far. |
13 |
|
14 |
Then I spent some hours fiddling with grub2, gummiboot et al to get that |
15 |
box booting up fine. dracut doesn't assemble the rootfs-raid etc etc ... |
16 |
-> fun |
17 |
|
18 |
What the question is in general: |
19 |
|
20 |
even if I manage to have it booting via UEFI from /dev/sda1 or so ... I |
21 |
still have this single point of failure as the vfat-partitioned ESP is |
22 |
on one physical disk only. |
23 |
|
24 |
I would like to set it up in a way that it boots even when the /dev/sda |
25 |
dies ... |
26 |
|
27 |
Maybe I have to go the BIOS way and have an ext2-boot-raid1 over 4 |
28 |
disks/partitions? I did that on other servers back then. |
29 |
|
30 |
What is the up-to-date and recommended way of achieving this? |
31 |
How do you gentoo-users do these things? |
32 |
|
33 |
I am still at the start with this server and don't mind backing up the |
34 |
rootfs and start from scratch with partitioning ;) |

Thanks, Stefan |
