I am a bit slow today. It seems like a dying drive should be replaced ASAP. Since you are using RAIDZ2, replacing the drive as described above should not be a problem. Is the issue that your hardware does not support hot swap and this is not a good time to shut the system down? Regarding the proposal to replace the drive with an external USB drive, this approach will surely "work" but since USB is only good for about 11 or 12MB/second, performance of the whole raidz2 vdev would surely suffer and writes would then be limited by USB speeds. It is likely to take quite a long time to resilver to the USB drive and if the filesystem is busy, maybe it will never catch up. It may perform better with the dying drive.
