I more or less tried that on my old 32-bit system. I installed a new disk and installed Fedora on a non-LVM partition. It could not see the LVM partition on the older disk -- same problem as I have now.
Ok lets try
shell# pvs
you must see line /dev/sdc2 and its VG name
shell# vgscan shell# vgchange -a y "VG name from pvs output" shell# lvscan here goes your ACTIVE "/dev/***" output shell# mnt "/dev/***" /mnt/fedora32
Here's what I get doing some of that:
################# [root@alan-fedora ~]# pvs PV VG Fmt Attr PSize PFree /dev/sdb3 vg_alan-fedora lvm2 a-- 2.73t 0
[root@alan-fedora ~]# vgscan Reading all physical volumes. This may take a while... Found volume group "vg_alan-fedora" using metadata type lvm2
[root@alan-fedora ~]# lvscan ACTIVE '/dev/vg_alan-fedora/lv_swap' [17.38 GiB] inherit ACTIVE '/dev/vg_alan-fedora/lv_home' [2.66 TiB] inherit ACTIVE '/dev/vg_alan-fedora/lv_root' [50.00 GiB] inherit #################
I don't see a VG name for /dev/sdc2.
I'm confused about what vgchange is supposed to do. The man page does not say what it does with the line you suggested. Specifically, the command takes an INPUT volume name, and the implication is that that name will be changed, but changed to what?
