I have a zpool consisting of several mirrored vdevs. I was in the middle of

I will be receiving the replacement drive in a few days. In the mean time, I
need the additional storage on my zpool.

Sure enough Cindy, the eSATA cables had been crossed. I exported, powered off,
reversed the cables, booted, imported, and the pool is currently resilvering

due to the controller not offering JBOD functionality I had to configure each
