Hi Dai, > Nils, it worked for me: > > pnfs-18-21.root[503] mount -F nfs -o vers=3,proto=udp > pnfs-18-22:/tmp/ipoib /tmp/mnt
This is really interesting, thanks a lot for trying to reproduce the issue. Though it is interesting so see that under some circumstances lockd does initiate the portmapper call via udp, this is not a solution for the problem I am working on because, for performance reasons, I need to run NFS over TCP. Would anyone be willing to improve the network lock manager code to make the transport protocol for the portmapper call configurable? For me, a simple tunable would be sufficient. Thank you, Nils
