You're right.  This is a tutorial.

> Nothing in the

The in-tree documentation explains the syntax of the admin commands and
the technical aspects of the subsystem.

> Do you have to create file systems on the 
> drives first? 

No you use the raw devices.

>  Do you have to use fdisk to slice them up?  

You can do that.  It is not required.

> Is there a size limit on drives?  

The size limit would be file-system related; not gmirror.  You're pretty
safe into the terabytes with UFS2

> I am trying to mirror two 400G drives, is this 
> supported?  

Sure, follow the RSE link you were sent.

> There is no information anywhere that I can find about these 
> topics.

Always search the mailing list archives.
