I have just had Fedora 7 re-installed on my work desktop as the old disk drive was slowly failing. I need to access the old disk if I can, it's still in the system and visible but the person who installed it didn't change volume groups so I have two disk drives with the same volume group. How do I change the name of the old disk's volume group so I can mount it and see it? Running vgscan returns:- Reading all physical volumes. This may take a while... WARNING: Duplicate VG name VolGroup00: Existing P6sqp0-rIos-JYmi-8L32-ymtN-LzB4-g5BdLL (created here) takes precedence over TdWFKp-H4tw-UrVq-Jmre-26hv-zmyE-IZXQLI Found volume group "VolGroup00" using metadata type lvm2 Found volume group "VolGroup00" using metadata type lvm2
Could you try vgrename? "man vgrename" for more info. From man page - vgrename /dev/vg02 /dev/my_volume_group renames existing volume group "vg02" to "my_volume_group".
Ah, but they're *both* called /dev/vg02 so that's no help.
However it turns out that vgrename understands UUIDs so the following works:-
vgrename TdWFKp-H4tw-UrVq-Jmre-26hv-zmyE-IZXQLI MyVolGroup
It's not immediately clear from the man page that this works, but it does - phew!
