MacMini RAID1 ESP UEFI (SOLVED)
MacMini RAID1 ESP UEFI (SOLVED)
I have a Debian 11 installation, where the partitioning and RAID1 configuration where done using the automatic partitioning of the Debian installer.
But when I try to finish partitioning and write changes to disk I get the following error.
What have I done wrong?
I already tried to google for a solution but unfortunately I was unable to find one...
Many thanks in advance for any hint

Re: MacMini RAID1 ESP UEFI
I see 3 RAID arrays but only 2 RAID partitions on each drive. Did you build the RAID1 device #3 (mounted on /) with the EFI partitions ? This is wrong. EFI partitions cannot be used as normal RAID members nor as the root filesystem. Also 500 MB for the root filesystem is too small.
If I were you I would create only one RAID array, use LVM on top of it and create logical volumes as needed (/, swap, /home...)
Re: MacMini RAID1 ESP UEFI
Actually I want to be able to boot from one or the other device automatically, if one fails, so I think LMV is not suitable or am I wrong here?
So I started again, resized root filesystem and installed Debian 11 on one SSD only and now I'm busy reading ton's of blog post's about mdadm and initramfs
My system has two hard drives, /dev/sda and /dev/sdb which are identical in size. /dev/sda is currently unused, and /dev/sdb has the following partitions:
This is the current situation.

Re: MacMini RAID1 ESP UEFI
LVM over a single RAID array is more flexible than multiple RAID arrays. It is orthogonal to boot redundancy and disk fault tolerance.
Create an EFI partition on each disk.
Create one (if you will use LVM) or several (if you will not use LVM) RAID partitions on each array.
Create RAID arrays using the RAID partitions.
Use the single RAID array as LVM physical volume or use the multiple RAID arrays as /, swap, /home...
If using LVM, create a volume group with the RAID array and create logical volumes for /, swap, /home...
Finish the installation.
The installer will use only one EFI partition so you will not have boot redundancy. This is when things get tricky. There are basically two different methods.
Method 1: have two independent EFI partitions, manually install GRUB on the second one and create/update EFI boot variables in the NVRAM with efibootmgr.
Method 2: create a RAID1 array with metadata 1.0 (at the end) on the two EFI partitions, format it as FAT, mount it as /boot/efi, reinstall GRUB without updating the NVRAM and manually create/update EFI boot variables in the NVRAM with efibootmgr.

Re: MacMini RAID1 ESP UEFI
I'm curious about how Ubuntu handled the boot redundancy though. Did it install GRUB in both EFI partitions and create two boot variables in the UEFI NVRAM ?
Re: MacMini RAID1 ESP UEFI (SOLVED)
Yes, I think it did install GRUB in both EFI Partitions, actually it created two small extra partitions (1GB)
I simply marked the each drive as a boot drive and left it unformatted and then created only one extra partition on each drive with the rest of the remaining capacity, left both unformatted too. Then I setup the RAID1, added and formatted it as ext4 and mounted it on "/", then the installer just took care of the rest.

If I were you, I'd check
- the contents of both EFI partitions
- the EFI boot variables (with efibootmgr -v)

Re: MacMini RAID1 ESP UEFI (SOLVED)
I wonder how it is set up. Are both EFI partitions mounted ? Where ? Usually an EFI partition is mounted on /boot/efi, but there is only one /boot/efi.
Also I'm curious about how the grub-efi-amd64 package knows it must install GRUB on both partitions on upgrades. Stored in debconf ?
Code: Select all
debconf-show grub-efi-amd64
EFI boot variables are usually not automatically deleted when a boot loader is removed.
You can mount them as any other partitions if they are not already mounted.
blkid will show which partitions have these PARTUUID 64190021-1613-40fc-8078-5ee74885e655 and f5877435-37c6-4081-a98f-62707c7fd6a3.
df or lsblk will show which partitions are mounted where.

I''ve now replaced the SSD I removed with a new one and now in the process of figuring out how to restore and rebuild the RAID to see if my recover procedure works...

To rebuild the RAID you need to partition the new SSD and add the RAID partition to the degraded arrays with mdadm.

STEP 4: Add new disk to RAID
Code: Select all
$ sudo mdadm --add /dev/md0 /dev/sda2
mdadm: added /dev/sda2
STEP 5: Watch resync process
Code: Select all
$ sudo cat /proc/mdstat
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md0 : active raid1 sda2[2](F) sdb2[0]
975526912 blocks super 1.2 [2/1] [U_]
bitmap: 8/8 pages [32KB], 65536KB chunk
unused devices: <none>
STEP 6: Write bootloader
Well here I'm getting a bit unsure and busy googling what would be the correct procedure...
I think to just give it a go as there is not much to loose and I can always start all over again, but I got stuck at Step 5
So that's it for the time being, will be back tomorrow

Re: MacMini RAID1 ESP UEFI (SOLVED)
As I suspected, the EFI partitions are recorded in debconf. The Debian bullseye package lacks this. Maybe in testing/sid ?
But according to earlier lsblk output only one EFI partition (sdb1) was mounted, so I wonder how does the package install or upgrade GRUB in sda1.
Can you show the contents of /etc/fstab ?
Too bad you removed the old SSD... It could have been useful to compare the UUIDs and PARTUUIDs.
The UEFI firmware will boot using any available EFI partition.
SquashFS filesystem images containing Snap packages. They neither belong to sda or sdb but md0 (RAID array containing the root filesystem).

- /dev/sda1 is supposed to be an EFI partition, not a RAID member. It must be formatted as FAT.
- AFAICS there is no /dev/md1 RAID array, only /dev/md0.
From what I can see, that should be done by reconfiguring grub-efi-amd64

Now I'm stuck @ Step 5, as the RAID still shows

Will continue tomorrow
Have a nice evening and thanks so far for the help, learning a lot, ver much appreciated

Re: MacMini RAID1 ESP UEFI (SOLVED)
It mounts only one EFI partition (on /boot/efi as usual). So I still don't know how GRUB is upgraded on the other one. Maybe the partition is mounted temporarily.
Can you show the full content of /proc/mdstat ?
Only sda1 (as FAT). As a RAID member, sda2 does not need to be formatted.

Re: MacMini RAID1 ESP UEFI (SOLVED)
Or this is the former sdb, and the former sda did not respond. Device names sd* are not stable and depend on the discovery order (which is not deterministic), so they may be swapped at each boot. You can compare the UUIDs, PARTUUIDs, model and serial number.
