Package: udev Version: 232-25 Severity: important File: /lib/systemd/systemd-udevd
Dear Maintainer, After upgrading to stretch I've discovered that some machines are taking a long time to boot -- more than two minutes -- with no immediately obvious cause. For example: > % systemd-analyze > Startup finished in 2min 55.491s (kernel) + 13.076s (userspace) = 3min 8.568s During most of this time, nothing appears on the console except a cursor. Kernel and system logs show nothing to pinpoint the issue other than long time gaps, e.g.: > [ 3.194336] clocksource: Switched to clocksource tsc > [ 121.499692] md: linear personality registered for level -1 Adding 'debug' to the kernel command line however I got this clue: > [ 64.386629] systemd-udevd[88]: seq 905 '/devices/virtual/block/dm-5' is > taking a long time After some further investigation it appears the problem stems from having an LVM PV inside another LV. Here is how I am able to recreate the problem on a fresh stretch install: > # lvcreate -n pvtest -L 1g $vg > # pvcreate /dev/$vg/pvtest (where $vg is some existing volume group name) Now rebooting the system will result in the long boot delay. This sort of setup did not cause any problems in jessie. An obvious workaround is not to put PVs inside other LVs, but this is sometimes a convenient arrangement and I would hope it could be made to work without an excessive boot delay. Thanks. -- Package-specific info: -- System Information: Debian Release: 9.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages udev depends on: ii adduser 3.115 ii dpkg 1.18.24 ii libacl1 2.2.52-3+b1 ii libblkid1 2.29.2-1 ii libc6 2.24-11+deb9u1 ii libkmod2 23-2 ii libselinux1 2.6-3+b1 ii libudev1 232-25 ii lsb-base 9.20161125 ii procps 2:3.3.12-3 ii util-linux 2.29.2-1 udev recommends no packages. udev suggests no packages.
