When you delete the file, the blocks are eventually freed provided that there are no snapshots holding onto these blocks. If the data was already contiguous, then you should have 10GB of contiguous free space. If the files were not, then... you get the picture.

WAFL does a very good job of keeping fragmentation out of the picture - however, if the filesystem fills up, this causes problems.

Hi all: Could tech gurus respond to this question: I am planning to clean up some space on the filer - say 10GB.

Since WAFL FS is intellegent minimizing the defrag issues, what happens on deletion of the files on my volume? If I delete 10GB of 50GB, will the FS still be fragmented, or WAFL does it auto when files are deleted? Do I will have to run defrag tools explicitly?

Thank you for your reply. Marge.
