My partition is both with LVM layer and LUKS encryption, which can’t not be resized when Opensuse mounted it as system point, so I am going to boot in LiveCD environment and do the operation but not all LiveCD is preinstall the necessary packages, and I don’t want to go online to get them, what LiveCD has been preinstall LVM and LUKS packages and do the operations with GUI application?
Any live Tumbleweed iso should work there.
Check the download page:
https://download.opensuse.org/tumbleweed/iso/
and look for iso with “Live” as part of the name. There should be KDE-Live, Gnome-Live and XFCE-live. Best to go with the x86_64 version if your hardware supports that.
