git-annex/doc/bugs/Inconsistent_results_between_git-annex-fsck_and_git-annex-whereis.mdwn

### Please describe the problem.

I'm seeing some inconsistent results between runs of `git annex fsck` and `git annex whereis` that I'm not able to explain. When I run `git annex fsck`, it reports a few keys that only have 1 copy, and advises me to make more copies. If I run `git annex whereis --key <key>`, git annex confirms that it only knows about 1 copy of this key. If I then use `git log --stat -S'<key>'` to find the actual file that it refers to, and run `git annex whereis <file>`, git annex report 9 copies of this file. Checking on remotes shows that these files do exist on the remote, so why does `git annex fsck` and `git annex whereis` mis-report the number of copies when querying for the key - but not for the actual filename? Additionally, `git annex find --lackingcopies 1` doesn't return any results, but should if there are actually files with not enough copies?


### What steps will reproduce the problem?


### What version of git-annex are you using? On what operating system?

5.20151208-1build1 on Ubuntu Xenial, one remote running 5.20141024~bpo70+1 on Debian Wheezy

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

I trust Git Annex to keep hundreds of GB of data safe, and it has never failed me - despite my best efforts
