Before allowing the ZED to mark a vdev as REMOVED due to a hotplug event confirm that it is non-responsive with probe. Any device which can be successfully probed should be left ONLINE to prevent a healthy pool from being incorrectly SUSPENDED. This may occur for at least the following two scenarios. 1) Drive expansion (zpool online -e) in VMware environments. If, during the partition resize operation, a partition is removed and re-created then udev will send a removed event. 2) Re-scanning the namespaces of an NVMe device (nvme ns-rescan) may result in a udev remove and add event being delivered. Finally, update the ZED to only kick in a spare when the removal was successful.
