Linux: “Found duplicate PV XXXXYYYYY: user /dev/sdb1 not /dev/sda1”

hard drivelinuxpartitionUbuntu

I'm trying to resize my virtual hard disk, so I've cloned it, and right now I have two disks in my virtual machine.

I'm trying now to boot off the old virtual disk and then resize the new hard disk's partitions, but when I do pvresize complains that there duplicate physical volumes (PV) with the same ID (presumably because I cloned my disk).

What do I do?

Can i just change the ID of one of the physical volumes?

Have you considered trying pvchange -u on the new physical volume to give it a new UUID?

Linux – Ubuntu: Resize the root LVM(2?) partition

In general, here's how to resize LVM volumes:

Let's say /mountpoint is on /dev/VolGroup00/mountpoint. You can find this out by checking out /etc/fstab or by running mount -l.

You may also need to resize the actual Physical Volume, depending on your setup. Use pvdisplay to find out if it's big enough, and use pvresize (much like lvresize below) if necessary.

umount /mountpoint
lvresize -L +<HOW MUCH BIGGER> /dev/VolGroup00/mountpoint
e2fsck -f /dev/VolGroup00/mountpoint
resize2fs /dev/VolGroup00/mountpoint <TOTAL SIZE>
mount /mountpoint

This amounts to umounting, resizing the underlying LVM, then resizing the actual ext3 partition.

A few things to be careful of:

Obviously playing with / will be different from a data partition. You may need a boot disk such as Sysrescuecd instead of Doing It Live. Also see Kristof's comment below -- you may actually be able to do this without unmounting /.
lvresize has a few different syntax options, and reducing a logical volume will probably harm the overlaying partition. Consult your local man pages for more information.
