I know you can't currently convert a RAIDZ1 into a RAIDZ2. I would rather run RAIDZ2. I have 3 x 3TB disks. So I can make a 2+1 RAIDZ1, or I can make a degraded 2+2 RAIDZ2 and add another disk later when I can afford it.
What are the implications, is there any difference, of running a degraded 4 disk RAIDZ2 with only 3 disks vs running a optimal 3 disk RAIDZ1?
