Pair of seagate 1G drives as mirrored, Freenas 9.1.1 .. one of the drives failed hard, I tried just sticking in another drive and it showed up in the pool as disabled. I probably screwed up by wiping the new disk and adding it to the pool as stripe. Anyway to recover?

Drive died, not in disk list .. how do I replace?

I attempted to do the replace, but there didn't seem to be a way to do so .. the bad drive was not being detected by the OS at all, hence didn't appear in the gui for me to click replace ..
Code:
[root@freenas ~]# zpool status
pool: mainpool
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas exist for
the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.

Yeah, you have 2 vdevs. One is a mirrored vdev, the other is a single disk.
You've made some serious mistakes.
First, you need to backup your data, pronto.
Now, here's the 2 mistakes I see.
1. You didn't create the pool from the GUI. If you are like most people you did it from the CLI and you shouldn't have.
2. Instead of replacing a failed disk you added the disk as its own vdev.
For #1, the only fix is to replace disks and hope you have enough space(statistically you might not have enough space unless you disable swap.. which isn't recommended but you have no choice)
For #2, the fix is to either destroy the pool or add another disk to the single-disk vdev thereby making it a mirror. (You will have to do this from the CLI because the GUI doesn't support this). You cannot remove a disk once its been added as a vdev.
Good luck!
Edit: If, at any point, your single disk vdev fails, you will lose the pool. This is why its imperative for you to make a backup.
