APAR status

  • Closed as program error.

Error description

  • In a file system with a million files spread across 10
    filesets.
    With gpfs 3.3.0.3, there is no difference in the amount
    of work required
    by the server between using mmbackup to backup a file
    system or a
    (fileset) subdirectory within the file system.
    The .execScript for mmapplypolicy does not contain any
    reference to the
    subdirectory.
    The list of changed or expired files created by
    mmapplypolicy does
    contain a subset of files within the subdirectory.
    The diff of the changed files against the old shadow does
    not contain a
    reference to the subdirectory.
    After that in tsbackup33, when the actual files are
    backed up or
    expired, the workload is reduced.
    

Local fix

Problem summary

  • mmbackup w/dir name still has applypolicy scan whole fs.
    

Problem conclusion

  • The solution for this is to add rule for policy module to scan
    only the directory and its dependents.
    

Temporary fix
