perfSONAR User Q&A and Other Discussion

[Joe Metzger <>]

Chris,
The "cannot stat" error is one that I have ran into as well.

One thing to keep in mind is that the install script doesn't
actually install things into the target directory you
specified.  It REQUIRES that you un-tar the distribution
into your installation target directory.

If you give it an empty directory as the location
to install, you will still have an empty directory after
the installation, and several scripts will have failed,
some of them silently, including the one that
creates the test MA config file.
