TI says the file system is secure - i.e., you could turn the machine off and on again and no files would be lost, and you could log in immediately. We seem to understand from DEC that we would need to run fsck before we could log in, and that this requires 10 minutes per disk. We have 12 drives. We don't have 2 hours to spare. Does anyone have any idea what these people are saying? i.e., did DEC write an implementation that doesn't use checkpointing and flush()? (These would ensure that what's to be done will get done, and what has been done was written to disk) Thanks Seth Rothenberg sr16@andrew.cmu.edu
