[gentoo-user] LVM2 Problems

Hi,

I recently synced my Gentoo (2.6.7-gentoo-r13) and after emerging
updated ebuilds, sure lvm2 was one of them and a reboot I lost my
mounted fs.

Fortunately I do not have / (root) under LVM however all efforts so far
haven't brought my fs back:

# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of
storage
# efficiency).  It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.

# <fs>                  <mountpoint>    <type>          <opts>
        <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.

Any further suggestions how to troubleshoot or fix the issue ?
