[linux-lvm] pvscan cant find my volume..

[Hjalmar Wåhlander]

Hi,

You guys got me nervous there for a while. 280gb of data down the drain? Nope.
I solved my problem with cfdisk ( fdisk would probably have done aswell ), 
I took my chances and rewrote the partition table ( an empty 
one            ), then pvcreate -ff and vgcfgrestore .. phew. Back online.


I hope someone can be helped with this solution.
