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?
