Fwd: how to deal with Incorrect metadata area header checksum in LVM
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:
Jt5E71u5LDUBOEbyPbKSAwYoHDth1lSa6HriQywmrKEuO4lVRT 5lBdar7LEm65jD
Incorrect metadata area header checksum
Volume group VolGroup00 metadata is inconsistent
Volume group for uuid not found:
Jt5E71u5LDUBOEbyPbKSAwYoHDth1lSaXl65MLs5oJFH9gPYo7 0eB9p7eVWUJ6SB

Volume group VolGroup00 metadata is inconsistent
Volume group for uuid not found:
Jt5E71u5LDUBOEbyPbKSAwYoHDth1lSaWgaUTHNB4qQZ900HNz VO8rPhbT8LhhWy

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.
