[chord] Can't insert folder - DHASH_ERR

[Alex Buie]

I'm trying to set up CFS, and I keep running into an issue where I
can't insert a filesystem. All of the data blocks are successfully
inserted, but then the final one causes a DHASH_ERR state.

root at wcd:~/sfsnet/sfsrodb# ./sfsrodb -d /root/files -s
/root/sfs-fdabek/what_cfs_key -v
export directory : /root/files
SK keyfile       : /root/sfs-fdabek/what_cfs_key

Here's the output from the log file:

If you have any ideas as to how to fix this, they're much appreciated.
