+After transferring many more files with `--force`, `git annex info` reports an available space of 17.46 terabytes, with following actual space:
+
+```
+$ df -h .
+Filesystem      Size    Used   Avail Capacity iused ifree %iused  Mounted on
+/dev/disk5s1    98Ti   2.3Ti    96Ti     3%     75k  1.0T    0%   /Volumes/ABYSS
+```
+
+I suspect the problem is either an integer overflow of some kind, or an integer size/precision error reading from the disk space struct in the disk space library.
