Subject: Re: [linux-lvm] How to resize a PV partition

I think the possible ways is:
1. Reduce the filesystem(resize2fs) to some minimal capacity a bit 
larger than the used size.
2. Do vgcfgbackup. Rename the backup file (for later use)
3. Recreate a smaller partition(larger than the filesystem capacity), 
and the new non-LVM
regular partition next to it.
4. Recreate an new PV on the partition(pvcreate -ff), and than create a 
VG with the orignal name.
5. Do vgcfgbackup again, use this PV information of Size and UUID to 
modify the old backup.
6. Restore LVM with the modified old backup file.
