I did solve this problem by doing a low level format of the disk... I also saw another thread where this bug was reported ... http://www.freebsd.org/cgi/query-pr.cgi?pr=3D130698 I have to find out now, how to indentify this potencial problem on my other servers, so I would know beforehand that a standard upgrade will not work. Cheers.
