LUKS cryptsetup error on each reboot/shutdown

Ask Fedora
1

I have my system set up with LVM on LUKS. On every reboot or shutdown, journalctl shows this error:

systemd-cryptsetup: Device luks-[UUID] is still in use.
systemd-cryptsetup: Failed to deactivate: Device or resource busy

It seems like I experience the same problem. I saw it when I tried to type my posting. Maybe I can just add it here? Lets see …

"With the procedure of reporting a bug I am not familiar yet. That’s why I want to ask you as community for some kind of review.

I setup the XFCE spin of Fedora 36 with the disk encryption option, but let it automatically do the partitioning (/ and /home as btrfs). Then I ran the updates.

The reboots and shutdowns take more time now.

With journalctl I was not able to dig up a lot of information. One hint is about cryptsetup that gets a 90 seconds timeout kill, because the device is still in use so the luks container cant be deactivated.

(thats too vague for a BR, right?)

My installations from about 7-10 days ago and before that did not show this behavior. It’s no problem to wait for the timeout. I would like to use this situation to learn and hope you teach me, how to gather more details.
