I have a zpool called storage that contains a five device raidz1 array.
Today I went and bought another 3TB device and put it in my enclosure. However, instead of creating a new pool and adding that device to it, I made a mistake and added it to my existing storage pool.
Now I have a top-level device that I want to remove called
sdg (that's the new drive). Every time I try to remove it I get:
cannot remove sdg: only inactive hot spares, cache, top-level, or log devices can be removed.
So how do I remove this device now? If this device fails, my entire pool will be unavailable. I'm thinking I should go buy another drive and at least it will be mirrored, but I just can't believe there isn't a proper way to do this.
This is my status dump:
