I have my laptop internal HDD where I will try to setup some raid so that I get some practice. I have this external HDD where I have already moved my home over and have already setup the mount points so that I get the external HDD copy of my home mounted when the computer starts and it is working.... now, my internal HDD has an LVM setup and I have already snuffed the home partition, which was setup in a LV eating up most of the room in the HDD. Now, I want to shrink the size of the VG/PV-Partition where it was setup so that I can then use the free space to get the RAID setup (and get my home back in the internal HDD).
I see a lot of articles around there about how to resize going up but I do not find anything relevant regarding shrinking out there after removing LVs. What would be the process involved to get this done?
