The Exabyte DN8500 drive we have on Ultra1 hung the SCSI bus, and this time resulted in massive file system damage. The damage was so severe that fsck couldn't run without core dumping. I had to hand edit the file system to get it to the point where we could run fsck. Right now there are 5000+ files in lost+found, we are working on restoring files that are missing. If you find some of your files missing please notify us and we will attempt a tape restore. We now have a second SCSI controller in the machine so that a tape drive hanging shouldn't hang the bus the disks are on.
