I have created a logical volume that has 2.5 TB of free space, out of a total of 7.9 TB. I have 8 RAID 0 devices which are 1 TB each. I'd like to remove 2 of these RAID devices from the logical volume since I don't need all that disk space. Is there a way to do this? I read about pvmove but it doesn't really match my scenario. I want to reduce the number of extents in my logical volume since I don't need them all, but I don't actually know what data is stored on the physical volumes, so I don't know what to pvmove. Thanks
