Hi, I just had some association in connection with the massive RAID failure (several old and a new SCSI disk) on Savannah: while you probably have already checked for this:
this sort of phenomenon strongly reeks of a problem with termination and/or cabling. Particularly since you report _one_ _new_ _disk_, it is quite likely that the corresponding change is responsible for the problem. Of course, this also implies a mechanical change with more possibilities for failures (controller no longer firm in slot, for example). -- David Kastrup
