  Fast(er) ANALYZE/DISK/REPAIR? 
 The Question is:
 
An old piece of software created over 65000 log files in a directory.  The
system manager removed these using "set file/nodir dirname.dir" and deleting
the directory file.
 
The disk has part of a constantly open database and a lot of user files, so
I have to clean up the mess without taking the disk offline for more than 1
hour.  Analyse takes about nine hours in tests on a similar machine.  Any
suggestions?

P.S. The disk is part of a shadow set (host based) if this is any help.
 
 The Answer is:
 
  You have a problem.  Several, in fact.  Ignoring the lack of a
  window, it would appear there are training issues involved.
 
  The files can safely remain in the system disk pending the next
  time when you can perform an ANALYZE/DISK/REPAIR, but they will
  continue to (unnecessarily) occupy disk storage.
 
  Depending on your level of interest, you could examine the file
  headers using low-level $qio calls to the XQP, looking for the
  footprint of a file in the now-missing directory.  You could then
  update the file header to reflect a valid file.
 
  Alternatively, see if the DFU package available on the OpenVMS
  Freeware can reduce the amount of time required to resolve the
  file structure problems.
