[linux-lvm] How to recover a VG from another PC?

Hi!

I've got the following problem:

I replaced an old SUSE 7.3, Kernel 2.4.10 (or so) by a current Debian 
with 2.4.23. There was an IDE disk:

/dev/hdc2            65      5005  39688582+  8e  Linux LVM

There was a volume group called 'ide' containing only this one partition.

Unfortunately I did the reinstall before reading the LVM manual and so 
did not use the export-feature. What I get from 'vgscan -d' is:

<333> pv_check_volume -- CALLED  dev_name: "/dev/hdc2"  pv: 804D110
<4444> pv_check_name -- CALLED with "/dev/hdc2"
<55555> lvm_check_chars -- CALLED with name: "/dev/hdc2"
<55555> lvm_check_chars -- LEAVING with ret: 0
<4444> pv_check_name -- LEAVING with ret: 0
<4444> pv_check_new -- CALLED
<4444> pv_check_new -- LEAVING with ret: 0
<4444> vg_check_name -- CALLED with VG: ide
<55555> lvm_check_chars -- CALLED with name: "ide"
<55555> lvm_check_chars -- LEAVING with ret: 0
<4444> vg_check_name -- LEAVING with ret: -348
<333> pv_check_volume -- LEAVING with ret: 0
<22> pv_read_all_pv -- device /dev/hdc2 NOT used

but no volume group appears.

What can I do?

Kurt,

send me <mauelshagen@redhat.com> a copy of the bzip2'ed output of
"dd if=/dev/hdc2 ibs=1k count=4k" and i'll have a go on your metadata trying
to repair it and send it back to you for VG recovery.

Cheers,
Heinz    -- The LVM Guy --
