SuSE nfs client RPC Timeouts
Hi,
i'm new to linux so bear with me.
we have two servers running in a cluster mode. i disable the cluster so that we could install a new os kernel that was provided by our vendor tumbleweed.
So the active server which does not have the upgraded os kernel the version is
Linux version 2.6.5-7.283-smp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Wed Nov 29 16:55:53 UTC 2006
on the passive server which has got the upgraded os kernel, the verion is
Linux version 2.6.16.60-0.39.3-smp (geeko@buildhost) (gcc version 4.1.2 20070115 (SUSE Linux)) #1 SMP Mon May 11 11:46:34 UTC 2009
for the server which does not have the kernel upgrade, i can mount to netapp mount. however from the server which has it's kernel upgraded, i get a rpc timeout error when i try to mount the drive.

somehow the server which has got the kernel upgrade is trying to use udp. the server goes through a firewall before getting to the netapp server and upd is not allowed.
in the fstab entries, i specified tcp,proto=tcp but no matter what values i put in, it's trying to use upd.
could anyone please assist.
Thanks,
Brian.
