Please try the 1.7.3301 installation package from

  https://www.auristor.com/openafs/client-installer

and see if you can still reproduce the problem.  However, I doubt it
will make a difference (see below):

I would also suggest that instead of using drive letter mappings that
you might try the flat unc paths

  //afs/.....

They say that the problem is not with the msys/cygwin layer but that
Win32 functions they are calling directly are returning a function not
supported error.   That could very well be.

They do not say what the unsupported function might be.  However, there
is a large amount of file system functionality that WinAFS simply cannot
support because there is no equivalent functionality in the AFS3 protocol=
:

  * extended attributes
  * alt data streams
  * windows security (acls)
  * certain dos attributes
  * cross directory hard links
  * oplocks

There are a variety of sub functions that cannot be implemented.

You do not say in your report whether this problem is new to the msysGit
2.x series or were you also experiencing it with the msysGit 1.x series
which relied more heavily on the msys/cygwin posix environment instead
of native Win32 file system calls.

I will look at some point but I cannot promise when I would get around
to investigating this issue.   If this is time critical you might want
to consider a paid support request.

In the release notes that are installed on disk (chm file) there is an
appendix with troubleshooting tips.  The first place to start is using
SysInternals Process Monitor to trace the activity from the git
processes to \\afs\.... and see which operations (if any) fail.
