• OSG Production meeting
• Campfire

  • NFS investigation: updating shared executable files on my NFS exports, programs running on clients all segfault. If you simply copy the new executable or library over an old version, you are violating the NFS cache consistency rules by changing a file that is being held open on your clients. Install program with the '-b' option.
