RAID configuration with existing disk without losing data is that possible?

[Matias Oltrabella]

Hello I have searched but I couldn't find info about this.
I currently have a FreeNAS 9.10 with a 4tb disc, I'm pretending to create a mirror raid, is there any way to do this without wiping the data on the actual disk? Any recommendations?
Sorry for bad english
Thanks

Export the pool in the GUI, import it in the CLI, add the mirror (see man zpool for details), export in the CLI and import in the GUI.

Doing that there is no need for backup the data? I know there is always need to perform a backup but that is not possible right now

Let me put it this way: It's no more dangerous than operating the pool as is.

Since you might have poor English, the command you want to use to transform an existing single drive pool into a mirror pool is zpool attach

Really thanks for the info, will try that when I get the disc
