Fwd: [help] how to deal with Incorrect metadata area header checksum in LVM

[Zhen Zhou]

Dear all,

I guess I did stupid way to handle the lvm.

Now the situation is:

root %lvscan
 Incorrect metadata area header checksum
 inactive          '/dev/VolGroup00/LogVol02' [114.22 GB] inherit
 inactive          '/dev/VolGroup00/LogVol01' [8.00 GB] inherit
 inactive          '/dev/VolGroup00/LogVol00' [8.00 GB] inherit
 inactive          '/dev/VolGroup00/LogVol03' [101.19 GB] inherit

root %  vgchange -ay VolGroup00

 Incorrect metadata area header checksum
 Incorrect metadata area header checksum
 Volume group VolGroup00 metadata is inconsistent
 Volume group for uuid not found:
Jt5E71u5LDUBOEbyPbKSAwYoHDth1lSa6HriQywmrKEuO4lVRT5lBdar7LEm65jD
 Incorrect metadata area header checksum
 Volume group VolGroup00 metadata is inconsistent
 Volume group for uuid not found:
Jt5E71u5LDUBOEbyPbKSAwYoHDth1lSaXl65MLs5oJFH9gPYo70eB9p7eVWUJ6SB

 Volume group VolGroup00 metadata is inconsistent

 Incorrect metadata area header checksum
 Volume group VolGroup00 metadata is inconsistent

 0 logical volume(s) in volume group "VolGroup00" now active

root % pvscan
 Incorrect metadata area header checksum
 PV /dev/sda3   VG VolGroup00   lvm2 [30.25 GB / 0    free]
 PV /dev/sda2   VG VolGroup00   lvm2 [101.16 GB / 0    free]
 PV /dev/sda1   VG VolGroup00   lvm2 [192.00 MB / 192.00 MB free]
 PV /dev/sda5   VG VolGroup00   lvm2 [101.22 GB / 1.22 GB free]
 Total: 4 [232.81 GB] / in use: 4 [232.81 GB] / in no VG: 0 [0   ]

Now I have no idea how to deal with it, I refered some articles:
http://www.novell.com/coolsolutions/appnote/19386.html, whatever I tried
'vgcfgrestore VolGroup00':

root  % vgcfgrestore VolGroup00
 Incorrect metadata area header checksum
 Incorrect metadata area header checksum
 Restore failed.

root % vgs
  Incorrect metadata area header checksum
  VG         #PV #LV #SN Attr   VSize   VFree
  VolGroup00   4   4   0 wz--n- 232.81G 1.41G

So what is the right path to recover these lvm?

Any tips will be welcome! Thanks in advanced,

BTW: the attached is lvm metadata file. More detail information
needed, pls tell me.
