"stornext" file system : too long file names lead to installation failures

I tried to install a long list of dependent software on a cluster with CentOS7 using spack 0.16.0.

1. The installation functions on a single Ubuntu-18.04 standalone system.
2. I tried to install on the home directory partition, which is located on an external StorNext filesystem. Even though the concretization was completed successfully, the installation exited after hours of installing most of the software with a KeyError when I tried to install. The final messages are given below.
3. I installed the software successfully on a BeeGFS partition.

Is there a problem using Spack on StorNext filesystems? What could be causing this and how can it be prevented?

$ spack -d -D /usr/users/rmeuer1/local/dlr/flowsim_gnu-eigen2-deps install

Start by reproducing the reported spack -d -D ... install command on the StorNext filesystem and read the traceback through lib/spack/spack/build_systems/python.py, lib/spack/spack/spack/filesystem_view.py, and lib/spack/spack/spack/environment.py. Trace the missing rst2latex.py path during view regeneration; done means the installation no longer fails with the reported KeyError and transactional-move error.
