Hello,
I was thinking about building a NAS using FreeNAS and had a couple of questions about how mirroring works.
I thought I would start out with 2 1TB drives mirrored using ZFS. If I pull a drive out, can it be read by any system that can read ZFS (since it is mirrored, I would assume yes)?
What happens when I go to add 2 more drives and extend the mirror (like a RAID10)? Can the existing data on the original mirror be redistributed to all 4 drives?
What happens if the original mirror is almost full before I add two more drives? Since the data would be written to all four drives, couldn't the first 2 fill up and cause issues?
Thanks for any answers you can give.
