In macOS High Sierra when booting a guest OS with a folder shared with the host over NFS it shows the wrong amount of files when amount of files grows. It didn't show the problem in macOS Sierra. Here's how you can quickly test it.
- Boot the guest OS with VirtualBox and SSH into it.
- CD to a shared NFS folder
$ mkdir test && cd test && touch test{1..1000} && ls | wc -l
This creates a test folder, goes into it and then creates 1000 test files after which it lists them and prints out the amount of lines in the output.
On my machine it prints out 1007 instead of 1000. It actually prints some files twice (and might not print others). You can check with listing only double files:
$ ls | uniq -c | grep " 2"
I believe this is an NFS bug or a kernel bug in macOS, could that be right?

It looks like a bug in mac os. Here's some related discussion https://github.com/hashicorp/vagrant/issues/8788
– Scott Jacobsen – 2017-10-02T21:10:10.2971It's an issue with APFS and NFS. Damn you Apple. Supposedly fixed by the upcoming 10.13.2 update – Benjamin R – 2017-12-04T03:24:42.833
