I then went into the Centos KVM in a separate terminal and did a "dd" write to the NFS volume in question. Watching the global zone terminal iostate output, I monitored what the %b (% busy) output was for each drive. One of the spindle drives was maxed at 100%. Sigxcpu (IRC username) suggested that this was the bad drive and I should try detaching it (This was one drive in a mirrored vdev). I then did a zpool detach zones <suspected bad device>. I then went back to my KVM termainal and re-initiated the dd write test. iostate in the global zone then showed even %b across all devices and my dd write test in the KVM reported a really good write speed to the NFS volume. Hope that helps.
