I have six client machines all accessing a single openafs server. The server
and five clients are running Ubuntu 9.10 with openafs 1.4.10. About 80% of
the time when a client modifies files on the afs, the changes are not
reflected on the other clients, even after the file has been closed (a zip
file is unpacked in a directory, replacing all identically named files). If
a new file is copied, often times the other clients will not see it.
Sometimes, after a couple minutes, the files are appropriately updated.
Oddly enough, the sixth client, which is running Ubuntu 9.04 with openafs
1.4.9, always has the changes properly reflected on it. However, I cannot
guarantee that the openafs client version is the issue as the sixth client
is not running in the same conditions (not in a virtual machine), and is
also running external to the local area network of the other four clients.
Is this expected behavior? I don't recall this being a problem when all our
servers were on openafs 1.4.9. Is there a way to force the synchronization?

Thanks,

Ken
