I'm trying git-annex for the first time and having some issues.

I have a WD MyBook 2TB Cloud Drive and using OSX Sierra.

I want to create an Annex on one the NAS smb shares and then a Amazon Cloud Drive replica for offsite backup.

When I run `git annex init` from the mounted share in OSX it fails with the below:

```
git-annex init
init
  Detected a filesystem without POSIX fcntl lock support.

  Enabling annex.pidlock.

  Detected a filesystem without fifo support.

  Disabling ssh connection caching.

  Detected a crippled filesystem.

  Disabling core.symlinks.

  Enabling direct mode.
A300 second timeout exceeded while waiting for pid lock file .git/annex/pidlock
```

Below are the results of `git-annex version`

```

Is it possible to have an annex on a SMB share?
