[Patrick Dupre]

Hello,

How can I manage such an issue?

WARNING: Duplicate VG name VolGrpSys0: 
s4LnbI-FRjU-fsPt-2W3d-XIIL-LT7o-uPsVfo (created here) takes precedence 
over 4Nyva1-5hZi-Mdgr-KnoK-7NMd-56y1-9jczSF
WARNING: Duplicate VG name VolGrpUsr0:

I guess by renaming your volume groups so you don't have duplicates (man 
vgrename). Be careful if one of them contains your / volume, you may 
need to rebuild the initrd and update your grub config if you rename it 
and update /etc/fstab if necessary.

Better to use the vgimportclone script as it takes care of the
numerous manual steps need to exclude one VG, re-UUID and re-name the
conflicting group.

# vgimportclone --help
Usage: vgimportclone [options] PhysicalVolume [PhysicalVolume...]
    -n|--basevgname - Base name for the new volume group(s)
    -i|--import     - Import any exported volume groups found
    -t|--test       - Run in test mode
    --quiet         - Suppress output
    -v|--verbose    - Set verbose level
    -d|--debug      - Set debug level
    --version       - Display version information
    -h|--help       - Display this help message

The manual page has more usage details.

Bryn.
