Add mirrored drive to existing ZFS install

[abulafia]

, your OmniOS example seems to be Sparc? At least the device names hint at that.

Nope - OmniOS is pure x64. I think SPARC is only catered for by Triblix.

Great thread, exactly what I was looking for.

One more question: Can I run the commands directly from OPNSense shell while booted or do I have to boot from an external drive?

All from the live system. For another complete walkthrough see

Thanks, worked nicely.

The only weird thing was, that gmirror load gave the following error message "gmirror: Command 'load' not available; try 'load' first.".
Don't know if it was because its is already loaded. (however gmirror unload gives a similar error).
In any case, I was able to complete the steps afterwards and gmirror status now shows me the swap mirror.
