Can you try to do something like

  tar cf - --one-file-system / | cat /dev/null

so as to force reading all the contents of the filesystem?


PS: I think the `cat' is not as useless as it appears because GNU tar
ha[sd]? some code to recognize when the destination is /dev/null and
avoids reading the files.  At least the Amanda backup service used that
feature at some point, IIRC.
