    UFS How do I access space freed by changing my UFS reserved space from 8% to 0%?

    I've run 'tunefs -m 0' and 'tunefs -o space' on my UFS hard drive, however I haven't seen any reclaimed space. The changes wrote successfully. It's a 4TB drive so I expect 3.725 TB but I'm getting 3.52 TB. Any thoughts?
