I created a 59.7TB Pool with 8x RAIDZ2, 8x RAIDZ2, 6x RAIDZ2, 2x Spare (3TB HD) The pool shows up at 59.7TB. This is exactly what I expected. Then I go to create a ZFS Folder and it says I only have 41.1TB available. Whats going on? The link below is a screenshot of the ZFS Folder creation in Napp-IT.
Side question, these are the speeds I'm getting. Is this good? Should I be doing something to optimize it? 20.48 GB in 70s = 292.57 MB/s Write 20.48 GB in 30.5s = 671.48 MB/s Read
