Currently I'm running a ZFS striped mirror set:
NAME STATE READ WRITE CKSUM
data ONLINE 0 0 0
mirror-0 ONLINE 0 0 0

mirror-1 ONLINE 0 0 0

gptid/21ddf484-33ad-6f43-c191-9f7ce4070677 ONLINE 0 0 0
mirror-0 and mirror-1 are striped. But I want to change it to a 2-disk setup, which is in mirror. Because the 2 disks in mirror-1 set are the biggest, I want to keep that mirror set. But I guess mirror-0 set contains data that is not stored in mirror-1 set.
So short question is, how do I change my config to a 2 disk mirror setup without losing data?
Thanks in advance!
