[SOLVED] Boot stuck "start job is running for /dev/disk/by-uuid/..."

Edit: Problem meanwhile fixed by systemd 255.2-3.

Hello!

After a recent

pacman -Suy

I find my system in a stucked boot screen that waits forever for a device by uuid (xxxxxxxx-e955-4d53-91ce-a78dd3abcc2b) that I've seen nowhere before in my system.

I'm having a full-encrypted system partition. Here's the mount layout:

$ lsblk -f

I've tried adding

rd.break=pre-trigger

or

rd.break=initqueue

to the kernel parameters to get into a rescue shell, but no way.
I don't know how to diagnose this anymore. I've restored my root from a backup snapshot for now.

Re: [SOLVED] Boot stuck "start job is running for /dev/disk/by-uuid/..."

Smells somehow like https://bbs.archlinux.org/viewtopic.php?id=290953 - all the way down to btrfs…
The UUIDs are not sensitive data, their purpose is to prevent reference collisions.

pacman -Suy

Ignoring the heresy (-Syu), what was updated?

Thanks for your reply, and pointing to the other thread.
Indeed, this seems to be a similar problem, especially with the unknown UUID.

Okay... IMHO they could also be used to identify a computer ;-)

From /var/log/pacman.log I've extracted the package upgrade information from below.
I've tried to downgrade to linux-6.6.4 again but this didn't help. I'm always on stock kernel.
Maybe it could also be the systemd version upgrade?

Re: [SOLVED] Boot stuck "start job is running for /dev/disk/by-uuid/..."

Maybe it could also be the systemd version upgrade?

Yes, there seem to be more issues w/ SD255…

If the downgrade doesn't help, try to add the UUID to your fstab as "noauto" so hopefully systemd will just ignore the device it made up.

IMHO they could also be used to identify a computer ;-)

It pseudonymizes (is that a word?) the system, ie. if you post that information in multiple locations, you can be tracked across those locations.
If you exclusively post it here along your user account, it's meaningless.

Yesterday, I did a new try with systemd 255.2 but the problem still exists - anyway, the boot does not get stuck forever, but continues after 2minutes.

I've then tried your advise, and added this to my /etc/fstab, but it didn't change anything.

# systemd BUG workaround:
UUID=xxxxxxxx-e955-4d53-91ce-a78dd3abcc2b	none	ext2	noauto

I've downgraded again to systemd 254.6 and put it on the IgnorePkg-list in pacman.conf, anyway this isn't a good solution. Should I file this to upstream?

Re: [SOLVED] Boot stuck "start job is running for /dev/disk/by-uuid/..."

As a mitigation, adding "systemd.gpt_auto=0 systemd.swap=0 noresume" will likely prevent it.
An interesting question to gage whether this is any different from https://bbs.archlinux.org/viewtopic.php?id=290990 would be whether only "systemd.gpt_auto=0 systemd.swap=0" will work (but I doubt it)

Re: [SOLVED] Boot stuck "start job is running for /dev/disk/by-uuid/..."

Hello all,

first of all, thanks for additional comments and I'm sorry for the delayed reply.

Today, I've updated my Arch Linux system again with the ignored systemd.

  1. After reboot, it totally broke with several other FAILURES and start jobs running, I think it has to deal with the D-BUS integration. The boot entirely got stuck here, I wasn't able to resolve it (and also don't have the time for it!).

  2. Then I booted into an installation medium, removed systemd from IgnorePkg and ran pacman -Suy again, so everything was up-to-date.

  3. This gave me again the version where I needed to wait 2min and the boot was normal (as reported above).

  4. I then added the proposed boot parameters from seth to the kernel parameters and it worked for now.

seth wrote:

Yup, that worked. Unfortunately, I don't have any swap now. I will try without systemd.swap=0 in a moment.

I think this is necessary.

Ok that's the current state for now. I'm reporting back if the systemd.swap=0 remove normally boots and gives me back the swap-space in a moment.

Ok, that worked. I now have swapspace and no interrupt during boot. Therefore systemd.gpt_auto=0 noresume satisfies.
I think this information is useful for the bug report to file to upstream.

Re: [SOLVED] Boot stuck "start job is running for /dev/disk/by-uuid/..."

Upstream claims this is fixed.
Is it actually still a problem w/ the latest systemd update?

Well, yes it happened today with this version:

local/systemd 255.2-2
    system and service manager
local/systemd-libs 255.2-2
    systemd client libraries
local/systemd-sysvcompat 255.2-2
    sysvinit compat for systemd

Can you provide a link to the ticket where it's flagged to be fixed?

Hey, thanks all your help.
Meanwhile, the problem seems to be fixed with systemd 255.2-3.
