Can't run Devuan Excalibur on Software Raid
Hi
I have a devuan on a software raid1. If i upgrade to excalibur i can't boot excalibur. If i install
excalibur with the netinstall iso it is the same. I can't run excalibur on software raid1.
My settings on daedalus are:
ls -al /dev/sd*
brw-rw---- 1 root disk 8, 0 10. Nov 17:01 /dev/sda

Welcome to the forum.

Re: Can't run Devuan Excalibur on Software Raid
Hi
Thank you stargate-sg1-cheyenne-mtn.
It doesn't help in my situation.
For testing purposes, I installed Debian Trixie on md1. I'm getting the same errors.
I have no idea why it's like that. And I've tried a lot of things. 
Okay, I'll keep looking ...
Is anyone here who is running Excalibur or Trixie on a software RAID?

Re: Can't run Devuan Excalibur on Software Raid
Have you verified uuid? it's unusual for me to see ":" rather than "-" in uuid, though it may well be an mdadm thing(?)
ls -l /dev/disk/by-uuidIn any case I'll set up a VM trial to see if I can replicate your problem.

Re: Can't run Devuan Excalibur on Software Raid
I've now set up a VM with 2 disks /dev/sda and /dev/sdb, with some 8 partitions each, to form 7 raid1 assemblies, while /dev/sda1 and /dev/sdb1 are set up as "BIOS boot" partitions for grub. Though only /dev/sd1 is in use for booting.
The key step for making it work is to not install grub via the installer but by hand from the C-A-F2 console, and then bind-mount /run from the installer onto
/target/run before the chroot into /target and the grub installation.
If you missed out on that, you can recover by starting the installer in menu choice 1, and progress that to the hostname dialog; then go to C-A -F2 console for recovery actions, for example:
# mdadm -C -n2 -x0 -lraid1 -v /dev/md0 /dev/sda2 /dev/sdb2
# mount -t ext4 /dev/md0 /mnt
# mount --bind /run /mnt/run
# chroot /mnt /bin/bash -iand continue in the chroot
# mount -t proc proc /proc
# mount -t devtmpfs dev /dev
# mount -t devpts devpts /dev/pts
# mount -t sysfs sys /sys
# mdadm --assemble --scan
# mount -a
# apt-get install --reinstall grub
# update-grub
# grub-install /dev/sda
# update-initramfs -u
# exitand then
rebootThe above is on the assumption that md0 has sda2 and sdb2, and contains the root filesystem. Further /etc/mdadm/mdadm.conf must be duly prepared; but the key is still to have md0 assembled in the console and then that /run is bind-mounted into the chroot before you go into that for the further rescue actions.

Re: Can't run Devuan Excalibur on Software Raid
@ralph.ronnquist, the mdadm report looks normal to me (example from Daedalus of four SATA disks raided in pairs)
mdadm --detail --scan
ARRAY /dev/md1 metadata=1.2 name=localhost:1 UUID=bbfe098d:4d1afad0:46f8d336:6e554bce

Is there a specific reason you are raiding individual partitions ?
Performance will suffer.
check /proc/mdstat to confirm raid integrity '[UU]' (healthy example from Daedalus)
cat /proc/mdstat

Re: Can't run Devuan Excalibur on Software Raid
Hi
First of all, thank you for your help. It seems I didn't provide enough information, sorry.
I was gentoo user from 2003 until 2018 before that redhat. Since 2018 I uses devuan.
But i have allways more as one dist on my computer. And always a debian on one partition.
Now i have on md0 daedalus, on md1 also devuan and on md2 debian bookworm.
I have been working almost exclusively with Devuan since 2018. Upgrade from ascii to beowulf to chimaera to daedalus without reinstalling.
I also always use software raid1. If one hard disk shows any error, I buy two new ones and replace both.
What I have found out so far:

Here's what happened:
Excalibur creates a RAID array from my partitions sda1 and sdb1.
See my output of fdisk -l, sda1 and sdb1 are not RAID partitions.
Later today i do a netinstall with Daedalus to check i am right.
Thank you

Re: Can't run Devuan Excalibur on Software Raid
You confuse me. What is the problem, really?
The installer doesn't build any md assemblies by itself. And the raid1 setup seems fine.
However the lack of a bootloader partition for grub on the boot disk is a problem. You should have /dev/sda1 or /dev/sdb1 partitions assigned as BOOT_bios partitions for grub to use (choosing which is the boot disk). So you can't use them in a raid and you can't install a filesystem on them.

Re: Can't run Devuan Excalibur on Software Raid
Confusing to say the least, and not least because of the large number of RAID'ed partitions... Likely in squarely in the "easy to fix if I was sitting in front of it, very difficult to diagnose remotely" category.
To (attempt to) clarify:
Where is your /boot supposed to be? Is it a RAID array? If so, which disks/partitions should comprise it?
Where is your boot MBR/PBR and where is GRUB stage1 installed?
Excalibur creates a RAID array from my partitions sda1 and sdb1.
See my output of fdisk -l, sda1 and sdb1 are not RAID partitions.
So sda1 and sdb1 are supposed to be independent devices, not part of an array? They contain duplicate but independent /boot filesystems, yes?
Partition type doesn't really decide whether a device is part of a RAID array, it's just a hint. Mdadm will scan for signatures and assemble what it can.
What does 'blkid' and/or 'wipefs -n' say about those disks (sda, sdb) and partitions (sda1, sdb1)? Do any of them have RAID signatures on them?
---
You should have /dev/sda1 or /dev/sdb1 partitions assigned as BOOT_bios partitions for grub to use (choosing which is the boot disk). So you can't use them in a raid and you can't install a filesystem on them.
Both "legacy" BIOS (MBR) and UEFI (GPT) can usually boot just fine from MDRAID1, since the RAID headers (v<1.1) are at the end of the member devices and they are otherwise indistinguishable from normal partitions.
The latter (along with putting EFI on MDRAID1) is very much "unsupported" though, and will require diddling with GRUB config and/or use of the '--removable' flag when installing EFI entries.
MBR just needs an MBR/PBR (and some free blocks for the stage1 loader) and a partition GRUB can read, UEFI just needs an EFI/ESP partition the firmware can read. RAID1 works for both.
For (NVME/GPT) example:
