I now found the correct starting sector: 51271920
The main clue I needed was the magic /^.{24}LVM2/, thanks for that!
and a friend of me who rewrote your code in python:
code by Michael Gschwanter:
#!/usr/bin/python
import re,sys
isLVM = re.compile("^.{24}LVM2") # This is how the Sector should look like
if __name__=="__main__":
args = sys.argv
device = args[1]
startSector = int(args[2])
howMuch = int(args[3])
endSector = startSector + howMuch
print "Searching for LVM2 on %s. From Sector %d to
%d"%(device,startSector,endSector)
dev = file(device,"r") # Read only, just for Security
dev.seek(startSector * 512)
t = 0
while t < howMuch:
sectorData = dev.read(512)
m = isLVM.search(sectorData)
if m:
print "We found the Start sector of the pv at %d\n"%(startSector+t)
break
t = t + 1
dev.close()
Usage: ./findlvm.py /dev/<deindevice> startSector maximumSectorsToTry
just used the output sector minus one!
Great thanks to all who tried and helped to save my data!!!
