[linux-lvm] Conflicting vg names but can't rename one



I took a drive from an ailing machine to suck the data out of it. This drive used to be part of a single drive LVM. Now, when I connect it to my machine, I realized I had named that vg the same name I had used in the vg I have in my desktop associated with just one drive,

vgdisplay export
WARNING: Duplicate VG name export: Existing fjM9qy-aCEM-iluj-yTdQ-CwT5-Iijk-uOYXlB (created here) takes precedence over SB3NfW-swQM-5rdw-xf5e-z6At-r5DM-dUwG7D

  VG UUID               fjM9qy-aCEM-iluj-yTdQ-CwT5-Iijk-uOYXlB

We see that UUID fjM9qy-aCEM-iluj-yTdQ-CwT5-Iijk-uOYXlB is the drive/vg in use while UUID SB3NfW-swQM-5rdw-xf5e-z6At-r5DM-dUwG7D is the extra drive I just attached to my machine. So I thought on using vgrename to change the name of the extra drive's vg so I can mount it:

vgrename SB3NfW-swQM-5rdw-xf5e-z6At-r5DM-dUwG7D export1

  Volume group "export" still has active LVs

What am I missing here? I thought if I told it to rename the vg with a given uuid I would be golden. As you can see, that is not the case.
