We're using the default /var/lib/cassandra as our data directory,
mounted as its own LVM volume. I don't see anything in cassandra.yaml
about a backup directory. There is an "incremental_backups" option
which is set to false.

Increasing the available disk space doesn't really seem like a
solution. We have only about 450MB of live data on the most
heavily-loaded server, and the space taken up by these deleted files
is growing by several GB per day. For now we can work around the
problem by periodically restarting servers to close the file handles,
but that hurts our availability and seems like a hack.
