First, backup and restore test any data you care about from the system.
Creating PVs will format a disk.
/dev/sda contains your root and boot partitions. Formatting these will make your system unable to boot or function. Reduce the file system and the partition is annoying: requires unmount in a rescue system, and will not be possible to reduce XFS file system. So don't reduce / if you can avoid it. When installing systems from scratch, make it small to begin with.
Develop a plan about how you are going to lay out storage and mounts on this system.
Currently, sdb is an empty PV of 931 GB, and sdc has a partition sdc1 of 112 GB containing file system /media/miki/main.
I suggest migrating to an all LVM setup for everything but / and /boot.
- Create a VG on sdb.
- Create LV and file system on it.
- Restore from backup /media/miki/main to the new LV.
- Create a different VG on sdc (no need to partition).
- Create additional LVs as required.
There are other ways you can design this. For example, its also possible to add both sdb and sdc into the same VG, then pvmove --name to migrate the volume back to the smaller disk.
