QUESTION: 238 You have a ZFS file system named /dbase/oral and you want to guarantee that 10 GB of storage space is available to that dataset for all data, snapshots, and clones. Which option would you choose? A. zfs set refreservation=10g dbase/oral B. zfs set quota=10g dbase/oral C. zfs set refquota=10g dbase/oral D. zfs set reservation=10g dbase/oral Answer: D Explanation: A ZFS reservation is an allocation of disk space from the pool that is guaranteed to be available to a dataset. As such, you cannot reserve disk space for a dataset if that space is not currently available in the pool. The total amount of all outstanding, unconsumed reservations cannot exceed the amount of unused disk space in the pool. ZFS reservations can be set and displayed by using the zfs set and zfs get commands. For example: # zfs set reservation=5G tank/home/bill # zfs get reservation tank/home/bill NAME PROPERTY VALUE SOURCE tank/home/bill reservation 5G local QUESTION: 239 View the exhibit.
