Salvaging the Networker media database

For Networker6 - first try to run "nsrck -mv"
====================================
The procedure of controlled corruption:

1. Run mminfo to write the records into readable format. For example:
   # mminfo > file or copy the mm into mm.old.
2. Media database compression:
   1. Shut down the daemons.
   2. Remove /nsr/mm/.cmprssd (if it?s there) and cmprssd.(and this file it will recreate again after you run nsrim -X (step5))
   3. Restart the daemons.
3. Media database scavenging:
   1. Shut down the daemons.
   2. Cause a "controlled corruption" by removing
      /nsr/mm/mmvolume/{*_i*, ss, vol}.
      The only file in you should see in the mmvolume directory when done are:
      ss.0, client.0, clients, vol.0, VolHdr ==>client.0 is for 6.x only
   3. Remove all the files under the directory /nsr/tmp
   4. Restart the daemons.
4. Run the following command:
   # nsrck -F (nsrck -L6 for Networker6)
5. When step (4) completes, run:
   # nsrim -X
