3 years ago, I extensively used the all-company's shared filesystem to pass information between 2 independent Jenkins instances (One on Windows for jobs that worked best under a Windows machine and one on Redhat which was considered as the "main" instance); and between the Jenkins and target application servers (Windows and Redhat) which all had the company's filesystem mounted. It took time to perfect, but worked wonderfully once I adopted the rename-in-place technique as described by parent.

I wonder if the system is still in place. Last time I checked the Jenkins folder was occupying 270 GB (!) of the 10 TB shared FS, most likely because FS block size was 1 MB.
