Sorry for not getting back to this sooner .... I've been busy :-(
To summarise: openSUSE11.0 sometimes (often) sees no response from a NetApp
filer,
but does not see problems talking to other (non-NetApp) file servers.
openSUSE10.2 and 10.3 don't have any problems talking to that same filer.
So the problem is specific to 11.0 and NetApp. Quite strange.
I will need to get some tracing information to find out what is happening.
Could you collect two things for me please?
1/ tcpdump -w /tmp/trace -s 0 host netappb1
start that running, then try to reproduce the problem, then interrupt the
tcpdump
and collect the "/tmp/trace" file. Compress it and attach it to the bugzilla
Hopefully it won't be too big.
2/ echo 65535 > /proc/sys/sunrpc/nfs_debug
echo 65535 > /proc/sys/sunrpc/rpc_debug
This writes trace information to the kernel log (it will appear in
/var/log/messages I think).
After the 'echo's, reproduce the problem, then echo 0 to both files and
collect the logs.
Probably best to do both of these at the same time. so start tcpdump,
do the two 'echo' commands, then reproduce the problem, then collect the
logs.
Thanks.
