How to edit/resize an LVM partition graphically (with a GUI)?

I want to resize an LVM partition (specifically, I want to increase the root / mount and decrease the /home), because I am running low on disk space on one virtual partition.  Now people say LVM has resizeable partitions… they claim, at least.  I did not see it so far… 😉 How can I do so? ### Blivet GUI I tried to use blivet GUI from a Fedora Workstation installation disk. So I: 1. boot that media 2. start blivet-gui (after installing it, if needed) 3. go to the LVM section and find the virtual partitions there. However, when I right-click and go to "Edit", the menu entries are all greyed-out. Fedora 31 ### Other tries Alternatively, is there any other GUI that can edit the size of the inner LVM partitions? I've tried gnome-disks, GParted and blivet.  GParted does only recognize the disks and GNOME disks does not help either. I want to avoid using the command line for this. ---- Cross-posted [at Ask Fedora](https://ask.fedoraproject.org/t/how-to-use-blivet-gui-to-resize-an-lvm-partition/6685?u=rugk) .
