You trim posts too much... there is no way to compare without opening another email.

No no no. Easiest way to do what you want to do: mdconfig -a -t malloc -s 3t -u 0 mdconfig -a -t malloc -s 3t -u 1
In what way is that easier? Now I have /dev/md0 and /dev/md1 as opposed to two sparse files.
Just make sure to offline and delete mds ASAP, unless you have 6TB of RAM waiting to be filled ;) - note that with RAIDZ2 you have no redundancy with two fake disks gone, and if going with RAIDZ1 this won't work at all. I can't figure out a safe way (data redundancy all the way) of doing things with only 2 free disks and 3.5TB data - third disk would make things easier, fourth would make them trivial; note that temporary disks 3 and 4 don't have to be 2TB, 1.5TB will do.
The lack of redundancy is noted and accepted.
