No, it's won't do anything automatically. You can't convert between RAID protection types dynamically. RAIDZ1 is not the same thing as a striped dev set in ZFS. I you're looking to change between types, you'll likely have to rebuild or backup/restore to the structure you desire.


I would judge from the man page description Print machine-parsable verbose information about the stream package generated that it is the same information, only in a better format (for example, bytes instead of conversion to KB/MB/GB). Also, from your example 4903284160/1024^3~=4.566, rounded up to 4.57, which checks out. Have a look at this Oracle ...

In summary it was clear that ZFS doesn't perform quite ...
