Problem details/scenario:                                              
- A directory, for example /test , is used as nfs filesystem mountpoint
- The nfs server file system contains, for example, file1 file2 file3  
- When the problem occurs, 'ls /test' command will result with message 
  ls: file1: no such file or directory                                 
  file2 file3                                                          
- At the same time, from other station, all three files are visable    
- Checking using 'lsof' command we can see two user process related    
  to /test path . Issue 'kill' command to those processes and issue    
  'ls' command again will show the expected results, i.e. a list       
  of all three files.                                                  
- Sounds like the problem related to linux caching mechanism and       
  occurs when file1 was changed on the server.                         
  However, the problem is intermittent, customer is unable to          
  reproduce it, neither was I.                                         
  The problem occurs for both, nfs and afs.                            
.

Comment 1 Bob Matthews 2001-05-22 15:20:29 UTC 
There's not much detail here, so I can only guess.

With AFS and NFS at least, there is no guarentee of consistency between the
client and server, or between two clients.  In order to understand if this is a
real problem, or just an misunderstanding about NFS and AFS inter-node
consistancy constraints, I need to have a concrete example of the set of
operations performed on the server and clients, and the order in which they were
performed.

If the problem becomes reproducible, a tcpdump or ethereal trace would be quite
useful as well.
