comment ZFS didn't expand free space after add
Well, autoexpand was off, which was the default configuration. I turned it on, ran zpool online -e zstorage <disk> for every disk, and ran zpool export and zpool import. After all of this, the problem still remains. It won't let me zpool online the vdevs "raidz1-0" and "raidz1-1", so I can't expand these. So in the end, I'm not sure that this is the solution.

Let me try and fix that last sentence... As I was writing I meant to say the problem "seems to be autoexpand" (having just noticed that on my pool), but now I'm not so sure that autoexpand is the fix either.

As I understand, the commands show the raw free space, not counting for anything that will be used for parity. Writing 2MB would actually consume 3MB with parity. In any case, I can say with certainty that the "free" space did not increase when I added the new disks, but the "available" space did.

I have 3 3TB disks and 2 1.5TB disks. This is for home use, and I don't intend to purchase any more disks. Now, that said, I absolutely would like to have the best configuration. :) Two-disk RAIDZ-1 is effectively the same as mirroring, is it not? I chose raidz simply because the other vdev was raidz, and I thought it didn't matter. Would 5-disk raidz-1 be the best option? I assume so, but this wasn't an option for me now since I started with 3-disk raidz. The problem seems out to be autoexpand, by the way. It was turned off, and I wasn't aware of the option.
