[systemd-devel] On /dev/disk/by-id/ata-...-part2 missing, again

[Alexander E. Patrakov]

Some time ago, I have complained that some boots are unsuccessful, 
because the /dev/disk/by-id/ata-OCZ-VECTOR_OCZ-Z5CB4KC20X0ZG7F8-part2 
symlink (which should point to /dev/sda2) is not created by udev in the 
initramfs (which uses dracut). Thankfully, people on IRC have suggested 
some useful debugging options:

systemd.log_level=debug rd.udev.log-priority=debug

So now I have a SOS report. It is over 1 MB, so not attached. The useful 
lines are:

[    3.026515] localhost systemd-udevd[319]: Unable to flock(/dev/sda), 
skipping event handling: Resource temporarily unavailable
[    3.027224] localhost systemd-udevd[333]: Unable to flock(/dev/sda), 
skipping event handling: Resource temporarily unavailable

Let me complain here that these error messages still don't contain the 
complete picture. How am I supposed to know which program in my 
dracut-created initramfs locks /dev/sda and interferes with udev event 
handling?
