how to check Raid configuration on freenas

[Rob_S]

Hi all,

I am fairly new to freenas and I am trying to understand how a FreeNAS server (ver 9.2.1.2) we inherited is configured in terms of RAID.
The server has 4 * 1TB disks but the space available appears to be 1TB, I would like to check the current RAID level but I don't seem to be able to find this information.
I can't get this information from either the View Volumes option or the ZFS volume manager.
Apologies in advance if this is has an obvious answer..

thanks,

Rob

Thanks for the quick reply Jailer,

the command shows 2 mirrors as per attached jpg (capture), what I still struggle to understand is why in the View Volumes section (Capture2) I see the size of the volume as 1TB (I would expect 2TB size).
it looks like I am using one mirrored volume of 1TB, how can I access the second mirrored volume ?

thanks,

Rob
