Not sure when or how it broke, as I know of people using it in production. There is a way to configure it for different versions of Ganglia, like 3.0, 3.1.

i have the same problem here, using Flume-NG 1.2 from CDH4.1.2.
I deleted all related RRDs, gmetad recreates them and i see those errors again.
Disk space, inodes, ... are fine. All RRDs not related to Flume-NG are fine, too.
These errors result in a gmetad crash after while (more metrics => earlier crash). If I disable ganglia support gmetad runs without any problem.

Looks like the RRD's are damaged, maybe the harddisk full?

I can't say for sure if this is a ganglia problem or a problem with flumes ganglia support. Anyone else feeding their counters to ganglia getting similar? Perhaps the ganglia ml may be more appropriate, not sure on this one.
