In response to reported connectivity problems between a Fermi file server and batch machines, Scientific Computing Services installed an upgraded operating system patch on the affected server and on a number of other hosts. This upgrade has improved connectivity for the Fermi production system.
Scientific Computing Services staff worked with our user community to discover and report a file corruption issue in our batch processing environment. The Red Hat vendor provided a solution which has now been deployed on approximately 1000 RHEL6 general batch farm systems, mitigating the problem.
