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?
Most likely you are either using a too old util-linux, whose use of
BSD locks conflict's with udev's use of it. (fsck -l)
Please always check README, it will let you know precisely which
release of util-linux you need at least.
I use fsck from util-linux 2.25.1. Verified by extracting the initramfs.
According to the README, this version should be OK, so it must be
something else.
Here is a list of files in my initramfs which, according to grep,
contain the word "flock":
