Error description

  • With AIX 5.3 TL09 (6.1 TL02) we added a sanity check to
    the
    mksysb command to proof if the files are still accessible
    after creating the archive_list.  When running savevg -r
    we
    don?t want to backup the files itself, only the volume
    group information and administration data files, but the
    sanity check still runs.  This adds a lot of time to the
    savevg -r execution time on filesystems with a large
    number of files, when we only want the volume group
    control data.
    

Local fix

  • Comment the find command of the sanity check section,
    which
     starts with:
    
    # Notify user that find command had problems where the
    archive list is incomplete.
    ...
    ...
    ${find} .$i ! -name "$tmp_file" ! -type s \( -fstype jfs
    -o -fstype jfs2 \) -xdev -print >/dev/null
    

Problem summary

  • SAVEVG -R TAKES VERY LONG FOR FS WITH LARGE NUMBER OF FILES
    

Problem conclusion

  • Appropriate code changes made to skip file sanity check loop
    when -r flag is used with savevg.
