Use rescue mode (you'll need to in order to resize the rootfs and partition containing the PV). Boot into rescue mode and skip the file system detection option then use lvresize or lvreduce to shrink the file system volumes and their file systems (specify the --resizefs flag - otherwise you need to do this as a two-step process, first shrink the file system with e.g. resize2fs, then shrink the LV that contains it). Once you've shrunk the LVs you can check to see if the PV can be resized - use pvresize with the --setphysicalvolumesize option to set the the PV to the intended size. If this step fails it will be because there are still extents allocated to some LVs that are using the space you want to free up (this is unlikely with the default Fedora layout but can happen with more complex VGs or VGs that have a lot of allocations taking place). If this is the case you'll need to use pvmove to relocate those extents elsewhere (see the pvmove man page). Once the PV has been reduced in size you can shrink the partition. Unfortunately there's no good automatic support for this today. Parted still insists on resizing file systems (but doesn't work with most common file systems..). I normally use fdisk: you'll need to remove (delete) the partition you want to resize and then re-create it with the same starting offset. The easiest way to do this is to use sector mode (default now) and make a note of the value in the start column before removing the original. If you're using a GPT partition table then you can do the same remove/re-add routine with parted but I prefer fdisk for MBR partition tables (again, use sector units when modifying the partition).
