Graph showing 1K instead of GB's about Disk's in Ganglia/RRDTool

Question

I'm using Ganglia and RRDTool to show charts in a web page. Everything is fine, but for some machines the graphs about DISK are with some kind of bug. Here is how they look in some machines (both machine are in the same cluster):

This one is correct, about the disk space:

But this one is showing 1.4Kb of disk space. Which is incorrect. How can I fix this ? Any idea ? I already uninstall it and install it many times, but it doesn't seem to fix the problem.

Answer 1

I got in touch with Ganglia Developers e-Mail list, they told me that the value is correct, which means 1.4K GB, which are 1400GB or 1.4T. I was all a misunderstanding. I just think it should be a documentation more clear about what are the metrics.
