Please help! Lost my LVM VG...

/var/log/messages doesn't contain any information about that problem.
The error happened too early during boot - so that the data didn't get
into the log files (disks were mounted in read-only mode).

Anyway, the problem does not appear anymore. I just restarted the
system several times (including complete power-down / power-up cycle),
to be sure.

I don't know what the reason was, but it seem to be fixed now!

Thank you very-very-very much for your help!!!
