[mdlug] LVM woes

[greenproc]

I accidentally have destroyed an lvm group.  My intent was to mount an lvm volume, but accidentally created a new one instead.  Now pvscan tells me there is an physical volume group using 0 of 9GB -- the expected size but not the usage.

Let this be a warning to those who are tempted to use lvm, but are not familiar with the proper use of the tools.  My original intent was to mount the volume
group with a live CD and back up the data -- the result was inadvertently deleting the volume group.

TestDisk has not been able to recover the partitions.  It looks like I have to do a disk dump and perform recovery on the raw data.  Any suggestions?
