I've copied the contents of 2 NTFS disks to my array (2 disks, no parity - will add later), and now I want to add these NTFS disks to the array but I could use a little affirmation.

 

I understand I don't need to preclear since there's no parity and think the steps are: enable "destructive mode" in the unassigned devices plugin, delete partitions, now I should have the format option, format to btrfs to match the disks in the array, assign to array, start array, enjoy. Is this correct?

 

Or can I just assign them, start the array, they'll appear as unmountable disks and I'll have the option to format them under "Array Operation"?

This, theoretically. I've seen instances where that didn't work well, but it should, so try it.

 

Just make sure the only drives listed for formatting are the ones you expect to format, as it's an all or nothing operation. Any disks listed as unmountable will be formatted.

That worked just fine, thank you.
