Extend LVM physical volume

Hi,

I have a task I'm not sure how to do from the information in the LVM man pages.

I want to resize a LVM Physical Volume, i.e. a partition that has LVM on it. I have some free space on the disk just before the LVM partition.

[ DOS ][ Boot ][***FREE***][ LVM ][Swap]

According to the pvresize man page, I just need to change the place used by the LVM partition to include the free space, e.g. using fdisk, and then run pvresize. However, I read somewhere that this will only work if the free space comes behind the existing LVM area. Is that right? If so, is there a way of moving the filesystem data from the end to the beginning of the enlarged space?

Making the free space into a new partition doesn't work since I already have 4 primary partitions.

Any ideas?

Regards,
Martin
