"Providing Extra Service: What To Do With Migrated User Files?"

National Energy Research Scientific Computing Center


When faced with decommissioning our popular C90 machine, there was a problem of what to do with the 80,000 migrated files in 40,000 directories and the users' non-migrated files. Special software and scripts were written to store the file inode data, parse the DMF database, and interact with the tape storage system. Design issues, problems to overcome, boundaries to cross, and the hard reality of experience will be discussed.
