would this be a reasonable course of action?

vgcfgbackup myraid

`take the size pvcreate reports and change the backup file accordingly`
vgcfgrestore myraid

Yes, this is the workaround.
(vgcfgbackup shouldn't be necessary though)

Being on the careful side here (don't want to restore 300GB of data). pvdisplay reports (after pvcreate): --- NEW Physical volume --- PV Name /dev/md0 VG Name PV Size 447.15 GB Allocatable NO PE Size (KByte) 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID wZQg66-cWrF-VDi5-GcRN-aYVg-RQQ3-PPm5K5

So how do I get the PEs? Can I also create a new Volumegroup without damaging anything? Or is there another way to get the total/free PEs?

Thanks for the insight,
