Thanks, It currently shows this:

Data: total=195.01GB, used=193.93GB
System, DUP: total=8.00MB, used=28.00KB
System: total=4.00MB, used=0.00
Metadata, DUP: total=1.75GB, used=385.41MB
Metadata: total=8.00MB, used=0.00

I didn't specify any RAID levels during creation. I'd like to have a
RAID0 installation across two hard drives.
