We have indeed changed this but it is supposed to work better now and
not break :-).
I have some questions:
* Which versions of
lvm2
lvm-common
udev
libdevmapper1.02
devmapper
do you have installed ?
* While it's broken, boot with break=premount, and do this:
udevd --verbose >/tmp/udev-output 2>&1 &
udevtrigger
At this point I think you will find that your mds and lvms
are not activated; check with
cat /proc/partitions
If as I assume they aren't:
pkill udevd
lvm vgscan
lvm vgchange -a y
mount /dev/my-volume-group/my-volume-name /root
If as you say this doesn't work, check the major and minor numbers
and symlinks shown by
ls -al /dev/mapper
ls -al /dev/.static/dev/mapper
ls -al /dev/my-volume-group
ls -al /dev/.static/dev/my-volume-group
dmsetup ls
and the output from
dmsetup table
and perhaps
mount /dev/.static/dev/mapper/vg-lv /root
When you've got it mounted
cp /tmp/udev-output* /root/root/.
exit
And then when the system boots attach /root/udev-output* and your
initramfs to this bug report.
* Does running
sudo update-initramfs
fix it ? (If you didn't attach it to this bug report as I ask
above please keep a copy of the old initramfs so we can peer
at its entrails.)
Thanks,
Ian.
