Seems that it tries to seek to some very high (and occasionally negative) block numbers and gets a "shouldn't happen" error. This happens in the middle of doing an epoch dump. I suspect this is due to the file system being active, and haven't looked into the problem very much yet. Fsck says things are fine. Has anyone else had this problem and/or solved it? Does anyone know how dump is supposed to deal with (what we used to call) "phase errors?" (when a inode points to different blocks between the begining phase of the dump when maps are made and the time the file is actually written to tape). As a great deal of long running (days) similuations are run on our system (with output going to the file system we wish to back up), we would like to avoid stopping these processes in order to do dumps. This used to be possible under older dump programs. Thanx, Gill Pratt ... alice!rabbit!physics!gill or ... gill@mc
