Ext2 by default reserves 5% of the drive for use by root only. That'd
be 45MB of your 907GB capacity which would account for most of the
discrepancy. You can adjust this with tune2fs.
plus, I think DataNode reports only 98% of the space by default.

There are no non-dfs files on the partitions in question.
df -h indicates that there is 907GB capacity, but only 853GB
remaining, with 200M used. The only thing I can think of is the
filesystem overhead.

Hey all,
I'm currently installing a new cluster, and noticed something a
little confusing. My DFS is *completely* empty - 0 files in DFS.
However, in the namenode web interface, the reported "capacity" is
3.49 TB, but the "remaining" is 3.25TB. Where'd that .24TB go? There
are literally zero other files on the partitions hosting the DFS data
directories. Where am I losing 240GB?
