    Solved How much space do I need to run portsnap fetch extract?

    Solved Change ZFS active mirror disk into spare disk?

    I have a machine with three 2TB drives mirroring the single zroot zpool. Is there a command sequence to pull one of those drives from the mirror, make the mirror forget it as a member of the pool and mark the drive as a spare rather than as an active pool member? A link to a page would be fine...

    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?
