On bootup, a race condition between the processes * kernel: md/raid * systemd-fsck can occur. Reproducible: Sometimes Steps to Reproduce: bootup/reboot Actual Results: The process systemd-fsck tries to check /dev/md* before the raid is properly assembled, resulting in file system errors. The bootup process stops and systemd enters emergency mode. Expected Results: Normal bootup in the following order: 1. assemble md/autoraid 2. perform systemd-fsck 3. mount partitions My system uses md software raid with autodetection on bootup. configuration: /dev/sda1 /boot ext4 /dev/sda2 / ext4 /dev/md2 /home ext4 (raid1 of /dev/sdb2 /dev/sdc2) /dev/md3 /var/tmp/portage ext4 (raid0 of /dev/sdb3 /dev/sdc3) The system ran fine for years in this configuration until a recent update. output of emerge --info: Portage 2.3.76 (python 3.6.9-final-0, default/linux/amd64/17.1/desktop/gnome/systemd, gcc-9.2.0, glibc-2.29-r2, 4.19.82-gentoo x86_64)

Created attachment 596844 [details] output of journalctl -b -o short-precise example of faulty timing of assembling/fsck on md3
Can you reproduce the problem with systemd-9999?
Seems to be fixed in systemd-9999. I did several reboots. Correct timing, no errors. Everything is fine now.
