Hello all, Just for posterity's sake, I was able to resolve this issue, by stopping the array, reassembling it using --force, and removing the device from udev using the Fedora docs I referenced earlier. I don't know if there is a way to resolve it without stopping the array, but if I read anything on the raid list that might be relevant to CentOS users I will pass it on. --keith -- kkeller at wombat.san-francisco.ca.us
