-Namenode doesn't accurately know datanodes free-space

I see that the Namenode always reports datanodes as having about 5% more
space then they actually do.
And I recently added some smaller datanodes into the cluster and the drives
filled up to 100%, not respecting the 5GB I had reserved for Map Reduce
with this property from mapred-site.xml:
Has anyone else experienced this behavior?
