You could try using vgimportclone, eg: vgimportclone -n newvgname /dev/sdb (replacing /dev/sdb with your new device name obviously) vgimportclone works by setting up its own little lvm environment where only /dev/sdb exists so it shouldn't get confused by the preexisting VG (which presumably has the active LVs that are causing lvm to get confused) Doesn't explain why it doesn't work in the first place though chris ----- Original Message ---- > From: Mauricio Tavares <raubvogel@gmail.com> > To: LVM general discussion and development <linux-lvm@redhat.com> > Sent: Friday, 17 December, 2010 17:27:13 > Subject: Conflicting vg names but can't rename one > > I took a drive from an ailing machine to suck the data out of it.
