I installed Fedora 24 on my main drive, but later decided to install it on my solid state drive instead. After doing so, I tried to mount my main drive (after running cryptsetup), but this happened:

# lvrename /dev/fedora/home /dev/fedora/althome 
  Multiple VGs found with the same name: skipping fedora 
  Use the VG UUID with --select vg_uuid=<uuid>

# lvdisplay

: above lists my partitions uuids


# lvrename --select vg_uuid=my-vg-uuid /dev/fedora/home /dev/fedora/althome

lvrename: unrecognized option '--select'

Since the given instructions don't work, how do I resolve this?

Use vgdisplay to find the volume group's UUID (not the logical volume's UUID) and then:

vgrename my-vg-id oldfedora

This appears to be a bug in Fedora 24.

TLDR - the only thing that works is:

lvm vgrename <vg uuid from vgdisplay> <new_vg_name>

Thank you to @koppor!

I too had two fedora_localhost-live VGs (pulled the drive out of a smoked machine and trying to get data off of it.).

I tried about 15 different combinations with vgrename then about 5 with lvm vgrename

The only one that works is this:

# vgdisplay
<snip>
  --- Volume group ---
  VG Name               fedora_localhost-live
  System ID
  Format                lvm2

Sorry for the late response. I guess this is some sort of bug. Instead of using --select vg_uuid=<uuid> use just the <uuid> of the vg. The vg_uuid can be found vgdisplay command
