I have two LUNs that I need to delete from my environment.  Lun 0 Lun 1.  The 2 LUNs have about 1 TB of allocatedspace  total.  If I delete these LUNs, will the space be reclaimed by the File system or the Storage pool?

Storage Pool has 1.2 TB of free space

The File System has 307.1 GB free space.

Which free space will change?  Both?
