Comment 9 for bug 109320

That's a serious bug. After installing Evms my lvm2 volumes could not be accessed anymore. So I tried to rescue them with Rescue broken system option from Gusty alternate cd. These are steps, which were necessary tu take in order to rescue system:

I got separate /boot and in lvm / , /home , /media , /var

1) From rescue broken system go chroot to / (in my case it was in lvm as mentioned above)
2) apt-get purge evms evms-cli
3) apt-get autoremove - to get rid of libevms-2.5
4) lvm
5) in lvm type -> vgcfgrestore
6) exit from lvm -> exit
7) depmod -a
8) update-initramfs -u
9) restart system
10) if your partitions don't mount edit /etc/fstab and change uuid to appropriate devices (in my case uuids were broken don't know why)
