ZFS zfs modes

[absduser]

I *believe* zfs is capable of operating under a couple (or more) modes: "performance" and "space"
much like ufs is capable of doing (space vs time).

I have a few questions about that:

What are these modes?

Do they automatically kick in at a certain % full?

Can I query what mode it's currently in?

Can I manually adjust these modes?

I'm wondering what made you believe that?

Can it be that you mix ufs it up with RAID configurations? As far as I know modes on ufs are non-existing. There are different configurations of RAID systems. Finally the RAID can hold a file system which might be ufs.

What are these modes?

With zfs(8) it is possible to configure properties for each dataset as compression or multiple copies of data. This is not possible with ufs. The configuration of the datasets do not change automatically. The handbook is a good reference for zfs, too. And as getopt mentioned, the documentation zfs(8) is really good. There are much more possibilities with zfs compared to traditional file systems.
