Interesting and horrifing somehow.

The Server was running fine for one year before our problems started.
And this includes the RAID10 configuration. So I guess the RAID10 cannot
be as unstable as I fear it to be. 

Ok, load on the server has risen since we bought the server, as I read
some comments suggesting the driver/hwardware becoming instable under
higher load.
