Environment

Novell NetWare 6.5 Support Pack 7
CaminoSoft migration software

Situation

Migrated files would demigrate from secondary storage back to the nss volumes during the backups. This problem happened after updating to spack 7. Previous spacks did not show the issue. This problem would result in disk space problems as all the files were demigrated back to the nss volumes. This happened with different tape software solutions.

Resolution

We found that when the tape software opened files with the LOCK IF DENY WRITE FAILS then the problem would happen. If we changed the open mode DENY WRITE which is a more strict version, the demigration did not occur. Changes were made to this tsafs to only lock the primary data stream if we're doing a stub+data backup. This will allow for any file open mode without demigrating the data.
