Maybe try running wireshark and watching to see if certain calls aren't getting responses. --b.

We have a client/server pair with both 1Gb and 10Gb network interfaces. I can mount the share on the client on the 1Gb interface just fine and interact with it normally. If I unmount and try to mount the share on the 10Gb interface, it will mount but everything after that hangs (like ls or df). The exports entry is the same on the server, i.e.: > > #1Gb interface > /data 10.10.10.0/24(rw,no_root_squash,async) > #10Gb interface > /data 128.196.X.X/28(rw,no_root_squash,async) > > I turned off iptables for troubleshooting and checked with the NOC here. Using NFSv4 by default and CentOS 6.10 2.6.32 kernel. I had some strange results if i try vers=3 or vers=2, then i can "ls /data" but if I try to "ls /data/subdir" then it hangs again. Now it doesn't even mount if i try with vers=3 or vers=2 >
