We recently had a most curious thing happened to our Sun server, I was wondering if anyone has seen this. I am interested in how to prevent this from happening again and how to fix it: Problem: A NFS client noticed, while performing a 'make', that many of her files (that reside on the server) had their contents swapped, i.e. the contents of file A now appears under the filename B, the contents of B appears under the filename C, etc. Hardware Configuration: Server is Sun Sparc 1+, running 4.1.1. The client machine is also a Sparc 1+, running 4.1. The Ethernet is twisted-pair. My Guess on What Happened: A glitch occurred over the network while the client is attempting to 'sync' with the server, causing the inode/ superblock table to be displaced or messed up. Even though contents of all the files should still be on the disk, I was not able to figure out how to recover them. I tried Sun's fsck and all it did was to eliminate some files that it did not like. Does anyone know why this occured. How to prevent it. And is there a way for recovering from such a problem? Any info/experiences would be appreciated. -- ------------------------- George W. Fleming gwf@sapphire.bellcore.com -------------------------
