Hi,
I have 2 servers which are connected to a gateway machine. The gateway and one
server are running
Linux 2.6.16.2, while the third machine is running 2.6.16.5. The two ethernet
ports on the gateway
which are connected to the servers are combined into a single ethernet bridge
device.
Ever since 2.6.16, I have noticed that I can no longer cross-mount the two
servers' /home
directories via UDP NFS. Which is to say that the mount command succeeds, but
that trying to
access the filesystem makes the process hang and the "NFS server not
responding" message to appear
in the console log. This is true regardless of which machine is the NFS server
and which is the
NFS client.
It all works fine if I use TCP NFS instead.
Also, UDP NFS works OK between any server and the gateway itself, so it only
goes wrong when UDP
NFS traffic is forwarded across the bridge. (I have not changed my firewall
rules, which just tell
the gateway to forward all traffic coming in from the bridge device anyway.)
Can anyone reproduce this, please? I obviously have a workaround (using TCP
instead of UDP) but it
sounds like there's a bug somewhere.
Cheers,
Chris
