[linux-lvm] Please help, [Incorrect metadata area header checksum]

[Ralf Sparr]

Jonathan,

thanks for the reply. I fixed the problem with 'pvcreate' & 
'vgcfgrestore'. The real problem sat in front of the keyboard
(as always :) ). I missed an argument for pvcreate. 
I didn't specify my physicalvolume, instead I put my vgname
'alice' instead of /dev/loop as an argument. After that, I
run vgcfgrestore and everything is fine again :)
