The file system has gotten totalled several times. Our Sun representative has told us that if either disk partition becomes more than 90% full, it is normal for all files on both partitions to be trashed without warning. Is this right? If it is, is there a way to prevent more than 90% of a partition from being used? He also said it could be trashed if a program tries to use too much memory, for instance with large arrays of real numbers. Is this true? If so, how can we prevent this? He has also said that after using doing a restore of a zero level dump, it is necessary to immediately do another zero level dump or the file system will get hosed again. Is this really needed? If so, can it be done overnight, to /dev/null? Please reply to me. I am not on both of these lists. ...Keith
