I had a core/md and two diskless MD's running and then upgraded to Beta4. Since then I have reinstalled the diskless MD the following two problems. First, I had to reinstall the diskless MD's and each required several tries but finally succeeded. Secondly, when I shut down the diskless MD's and tried to restart them each will time out. I have deleted them several times reinstalled with some failures and retries and finally got them to install again. After turning them off, once again they will time out.
