[linux-lvm] vgscanfailed"novolumegroupsfound"

[appendix at hatsune.cc]

Hi!

I've a LVM one physical volume "vg0" that created on 9 RAID devices.
It worked still the day.
But one day, I have problem about vgscan reports that it can't find my VG. 
And recovery data /etc/lvmconf/vg0.conf was broken by other cause.
Please help me..... or give me hints to recover it.

My VG structure is following

/dev/md2,md3,md4,md5,md6,md7,md8,md9,md10 => vg0

Kernel Linux melody.angelic.jp 2.4.5 #10 SMP

The pvscan report is following
>pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/md2"   is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/md3"   is associated to an unknown VG (run vgscan)
