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.

Temporary fix
