Bug#878162: fixed in systemd 232-25+deb9u2
The fix for this bug broke the IPv6 networking on one of my systems. When the RA does not include any MTU information, this patch causes no IPv6 default route to be added at all, leaving the system without IPv6 connectivity. The journal in this case shows: systemd-networkd[397]: eno1: Failed to get default router MTU from RA: No data available A workaround is to add MTU information to the RA from the router, but I don’t think this should be necessary. -- Rob Leslie r...@mars.org ___ Pkg-systemd-maintainers mailing list Pkg-systemd-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-systemd-maintainers
Bug#867368: systemd-udevd: delays boot for 2+ minutes when LVM PV is inside a LV

I initially thought so too, but attempts to debug the kernel with e.g. 'initcall_debug' were not fruitful. Instead indications point to something happening in early initramfs userspace. > Can you try booting with the old jessie kernel? This looks like a kernel > regression. I have confirmed that the problem still exists even when booting a stretch system using the most recent jessie kernel. I have tried modifying the initramfs scripts to arrange for systemd-udevd to be passed the '--debug' option. Here are some relevant excerpts: > % grep 793 systemd-udevd.debug > seq 793 queued, 'change' 'block' > seq 793 running > seq 793 '/devices/virtual/block/dm-2' is taking a long time > % tail -n 5 systemd-udevd.debug > giving up waiting for workers to finish > event loop failed: Connection timed out > Unload module index > Unloaded link configuration context. > timeout '/sbin/lvm pvscan --cache --activate ay --major 253 --minor 2' This of course suggests the problem may actually lie with lvm2. Please feel free to reassign if you agree, or suggest a further course of investigation.

Bug#867368: systemd-udevd: delays boot for 2+ minutes when LVM PV is inside a LV
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.
