NFS Error: no route to host

  • Follow


Hi there,
My NFS server is running well for most clients.
But for some client machines, such as, some RHEL5, and a freeBSD, I get 
error as below for some nfs mounts when the system is booting up:

Mount to ...  failed. System Error: no route to host

It's Okay to mount any nfs to directories directly under root (e.g. 
/mtpoint1). The error only occurs for mount points which are subdirectories 
(e.g /opt/mtpoint2).
However, I can manually mount them without any problem when the system has 
booted up. I am sure the nfs entries under /etc/fstab file are Okay becasuse 
I can simply run "# mount /opt/mtpoint2".

Any idea would be appreciated,
Ross

Prehaps network connection isn't negotiated yet at this point, for
example init-script starts pppd which immediately returns while
connection itself takes place in background. Same for the wireless.

Anyway, "no route to host" is an IP-level error, so I'd suggest
triple-check everythong network-related at this point, like plugging
simple ping or tcpdump tests right into the nfs initscript.

Now that seems irrational, stroke of luck, prehaps?)

That's one more point for "network delay" theory ;)
