According to newfs and tunefs the option -m (the percentage of space held back from normal users): "Settings of 5% and less force space optimization to always be used which will greatly increase the overhead for file writes".
Can it be set to 0% without losing performance — since there is...
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?
