Error "mdadm: No arrays found in config file or automatically" after updating

[DrJuanNadie]

First, thank you for your attention and please forgive me if my lack of knowledge makes you waste your time.

I just updated my system using:

Code Select Expand

sudo apt update
sudo apt --solver 3.0 full-upgrade

Previously, it was fairly up to date, from one week ago or less.

After finalizing the update without errors, I rebooted and I got the following messages:

Code Select Expand

mdadm: No arrays found in config file or automatically
... repeated a bunch of times ...
mdadm: error opening /dev/md?*: No such file or directory
mdadm: No arrays found in config file or automatically
... repeated a bunch of times ...
Gave up waiting for root file system device
mdadm: No arrays found in config file or automatically
Gave up waiting for root file system device.  Common problems:
  - Boot args (cat /proc/cmdline)
    - Check rootdelay = (did the system wait long enough?)
  - Missing modules (cat /proc/modules; ls /dev)
ALERT!  UUID=nnnnnnnnn does not exist.  Dropping to a shell!


nnnnnnnnn is in reality the UUID of my root partition.

Then it opens a shell that doesn't work (maybe because I use a cordless keyboard) and the system does not start.

After restoring the system to the previous state (using Timeshift) I tried updating everything but the kernel (I do this using Synaptic packet manager), but the same thing happened after rebooting.

I have the same problem (see other thread).

But I bet it's NOT the kernel (alone), but one of the new packages. kernel 6.10.5-1 was running fine during today d-u, but failed with reboot. So did kernel 6.10.6-1. BTW, the shell this failed boot ends in is dead here, too. Keyboard not working!!!

Debian standard kernel 6.10.4-amd64 still working.

Have a look into Posting " Topic: [DE] dracut-install: symbol lookup error" [https://forum.siduction.org/index.php?topic=9434.0].
It contains the reason and the cure(s).
I would/did prefer the "kmod" solution.

[michaa7]

Yes, this worked:

Code Select Expand


# apt install kmod=32+20240611-1  libkmod2=32+20240611-1

# apt-mark hold kmod libkmod2

Danke!

[DrJuanNadie]

Thank you for your answers. I read them as well as the related other topics of this same forum and Debian's and I understand that the problem is solved with packages kmod and libkmod2 version 33+20240816-2, which are already in the Debian's repos.

Consequently, I executed a full upgrade. The system booted well afterwards.

It is worth noting, though, that at the time of my upgrade the aforementioned packages were held to their previous version 32+20240611-1 and not upgraded, as you can see below (section "Not upgrading"):

I guess we will have to wait for the repos to "unhold" those packages to see if everything is back to normal.

It's just kmod now. But watch the removals -- you need initramfs-tools and initramfs-tools-core.

[michaa7]

...

Does this mean we don't need to hold back kmod any more because its now all fixed and handled accordingly by the Debian maintainers?

For what it says on Debian's forum (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1079022#124), yes it does.

[ro_sid]

@michaa7, @DrJuanNadie:
But only "now", where dracut-install in version 103-1.1 is available. Previously it could have been fatal [too many removals of important packages].

[DrJuanNadie]

The new packages are already in Debian's repos and they work fine.

I just upgraded my system. No package was held back and the system upgraded and rebooted well.

thanks I did find it,
but it seems to be obsolete now as the bug is fixed ?

seems so, link was meant as hint for possible future package searches ;-)
