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)
pvscan -- inactive PV "/dev/md4" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/md5" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/md6" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/md7" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/md8" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/md9" is associated to an unknown VG (run vgscan)
pvscan -- inactive PV "/dev/md10" of VG "vg1" [4.48 GB / 4.48 GB free]
pvscan -- total: 9 [68.48 GB] / in use: 9 [68.48 GB] / in no VG: 0 [0]
The pvdata report is following
