(The word wrap destroyed that, but the report for the LVM indicates 4% 
inodes in use.)

I'll maybe try that.

Thank you very much for the clues, which I think have provided some 
evidence for thinking the fs looks ok, with these reports, and with 
the static test of a 4GB iso transfer.

I may also try to run a backup with some enhanced logging.  I'd 
particularly like to see what rdiff-backup calculates the next 
increment to be - perhaps it thinks it has 'lost' some tranche of data 
and needs to copy or diff it again.
