Bugzilla Bug 84463

After I updated my system it no longer booted correctly.

To work around this problem I added 
=sys-fs/lvm2-2.00.33-r1
to /etc/portage/package.mask and re-emerged lvm2 (and got the previous version which doesn't dynamically link against the lib in /usr).

Reproducible: Always
Steps to Reproduce:
1. /usr is an LVM partition
2. emerge lvm2
3. reboot

Actual Results:  
system failed to fsck because the LVM partitions were not active.
The LVM partitions were not active because vgchange was dynamically linked
against something in /usr (I think libgpm)
/usr was unavailable because it was an LVM partition that didn't get fscked or
mounted.

Expected Results:  
boot normally

please do a ldd /sbin/lvm on the 2.00.33 version.

there is a new 2.00.33-r2 ebuild that builds statically by default because the
files are in /sbin.  Please let me know if that fixes your issues.

To those who have been bitten by this bug, you can repair your system with a
little work.  This info is distilled from

http://www.gentoo.org/doc/en/lvm2.xml

Boot from a liveCD.  I still had the CD-RW I used to install gentoo in the
first place.  We are not re-installing, just giving ourselves a working copy of
LVM.  Then I activated LVM and mounted my filesystem heirarchy (you will most
likely have to adjust your mount commands since these are for MY system, not
yours) using the following commands:

modprobe dm-mod
vgchange -a y

# adjust these for your system
mount /dev/hda3 /mnt/gentoo
mount /dev/vg0/lv_usr /mnt/gentoo/usr
mount /dev/vg0/lv_var /mnt/gentoo/var
mount /dev/vg0/lv_home /mnt/gentoo/home

chroot /mnt/gentoo

echo =sys-fs/lvm2-2.00.33-r1 >> /etc/portage/package.mask

emerge -pv lvm2
emerge lvm2

ldd /sbin/vgchange

  And make sure it isn't dynamically linked against something in /usr still.
Once the new version of lvm is installed in /mnt/gentoo, you may reboot and
eject the CD, and you should have a bootable system again.

The 2.0.33-r2 ebuild appears to solve my problem.

newer ebuilds fix this issue
