The storage SLA definition is:
((<storage_used_blocks> * 100)/<storage_block_count>)
substiting the values (the numbers in the brackets above) we get:
((0 * 100)/0) = 0/0
That sure looks like division by zero!

and JFFNMS agrees.
This interface is polling anf returning zero for everything, that's you
problem. the rrd analyzer is just kicking up a fuss about it.
OK, next problem.

whoa, where is that coming from?
Check your SLA Individual Conditions, especially item 26.
