Hallo,

I had an VG called 'vg01' which contained the only PV /dev/hdc

My problem happened during a system upgrade, where I could have removed the VG from the system or something else happened...

I do have an VDA backup /root/lvmconf/vg01.conf (attatched to this mail)

Is ist possible to recrate or restore the PV metadata? I believe that the data stored on this PV may be still there ...I hope so.

I searched the last two months for an sollution, but found nothing using google, diverse mailing list archives, heise-forum, etc ...

does someone on this list have any tip?

I would be very, very happy if someone could post some hints to try...

Yours Malte

pvscan & lvmdiskscan don't recognise either the PV nor the VG 'vg01':

------------------------------------------------ coldfusion:~ # pvscan pvscan -- reading all physical volumes (this may take a while...) pvscan -- ACTIVE PV "/dev/sda2" of VG "vgraid5" [447.09 GB / 428.59 GB free] pvscan -- ACTIVE PV "/dev/sdb" of VG "vg05" [76.69 GB / 0 free] pvscan -- ACTIVE PV "/dev/hda2" of VG "vg00" [2.21 GB / 0 free] pvscan -- ACTIVE PV "/dev/hda4" of VG "vg00" [13.92 GB / 564 MB free] pvscan -- ACTIVE PV "/dev/hdb1" of VG "vg04" [57.27 GB / 0 free] pvscan -- total: 5 [597.19 GB] / in use: 5 [597.19 GB] / in no VG: 0 [0]

------------------------------------------------

/dev/hdc shows 'free whole disk', but was in the past 'USED LVM whole disk'

pvdata shows this:

pvdata -- can't seek to volume group struct physical volume "/dev/hdc"

------------------------------------------------

I attached 'vgimport -fdv -v vg01 /dev/hdc' - maybe this clould help?

which other info are usefull ?

could someone give me a hint, what to do?
