does it momentarily offline the disks? like they re-appear in /dev within moments? That would be similar behavior to what I am experiencing, the disks drop from the array, but they are in /dev by the time I get a chance to see them. I am however not running smard to my knowledge, smartmontools is installed and I access it through the webmin module, but checking the drives with that and the array failures have not happened at the same time.
