If a pool contains a replacing vdev with a spare child, then any "zpool add" command will fail. It doesn't matter whether you're adding a regular vdev, log, cache, or spare vdev. The bug is in get_replication in zpool_vdev.c in the zpool command. zpool status bar pool: bar state: DEGRADED status: One or more devices is currently being resilvered.
