Hello,
the 40TB are in an filecluster and this machine is part of this. the system consists of 6x3tb in sw raid5. there are four partions on each machine. one with 100mb for the efi bios, one for the os in raid1, one for the swap in raid5 and one for the files in raid5. the machine was opened and the disk layed beside, i moved two disks slightly and in this moment both spinded for a second down and the raid was gone. there was no filetransfer but the raid couldnt rebuild because of missing two disks.
