NFS Stale File Handle error and solution
Sometime NFS can result in to weird problems. For example NFS mounted directories sometimes contain stale file handles. If you run command such as ls or vi you will see an error: First let us try to understand the concept of Stale File Handle. Managing NFS and NIS , 2nd Edition book defines filehandles as follows (a good book if you would like to master NFS and NIS): A filehandle becomes stale whenever the file or directory referenced by the handle is removed by another host, while your client still holds an active reference to the object.
A WebMaster’s view of Eclipse.org » Blog Archive » What is my NF
If you've worked on a *nix system, you're likely familiar with the /etc/passwd file -- the main list of accounts on that system. Although eclipse.org does not use the passwd file for user accounts, examining the compatible getent passwd tells the story about who was involved in setting up the original dev.eclipse.org way back in 2001. Keep in mind that we delete accounts of committers who have been completely decommitterized; therefore, the people you see mentioned below are still active participants in the Eclipse community even after 10 years . I wasn't there in 2001, but judging by her UID=500, I'm guessing Kim Moir was the one who inserted the first Linux CD in the drive and installed a computer called "dev.eclipse.org".
Fallacies of Distributed Computing - Wikipedia, the free encyclo
The Fallacies of Distributed Computing are a set of assumptions that Peter Deutsch and others at Sun Microsystems originally asserted programmers new to distributed applications invariably make. These assumptions ultimately prove false, resulting either in the failure of the system, a substantial reduction in system scope, or in large, unplanned expenses required to redesign the system to meet its original goals. [ citation needed ] Ignorance of network latency, and of the packet loss it can cause, induces application- and transport-layer developers to allow unbounded traffic, greatly increasing dropped packets and wasting bandwidth. Complacency regarding network security results in being blindsided by malicious users and programs that continually adapt to security measures. [ 2 ] Multiple administrators, as with subnets for rival companies, may institute conflicting policies of which senders of network traffic must be aware in order to complete their desired paths.
Linux NFS faq
Does your application open its files with the O_SYNC option? That will force NFS Version 3 to behave exactly like (synchronous) NFS Version 2. UDP requires IP fragment reassembly. If you see fragmentation errors indicated in the output of netstat -s you may want to increase the size of your socket buffers. Have you started enough NFS daemons?
