My research suggests that NFS client mounting is kernel-based, so
that's why I'm posting here. If there's a more appropriate list to
post to, I apologise, but I am not a list member.
I'm having a bit of a problem doing simple copies over an NFS mount.
The client is running Linux (2.6.11), and the server is running
Solaris (5.8).
When I first boot the client, getting NFS directory listings works
just fine. But the instant I try to copy a file (to or from), the NFS
mount hangs. While I can still do other network activity (even rlogin
to the server), any NFS access I try to do after that point hangs,
including directory listings.
I have had this same client and server working flawlessly for years.
The only change is that the client is now on a VPN (Watchguard SOHO
box). However, I have a Sun machine on the same VPN network segment,
and it can copy files with no problem, so it's not the router/SOHO
that's blocking anything. (NIS and DNS also work just fine for both
machines.)
Also, after it hangs like that, I cannot reboot the machine normally.
When attempting to unmount the network filesystems, the shutdown
hangs, and I have to hard-reset the machine.
Is there anyone who could please help me to debug this problem? As
far as I know, I have NFS setup properly, but I don't know enough
about it to know what options I might try. I don't even care if the
fix degrades performance; I just want it to not hang.
Does anyone have any ideas?
Thanks very much in advance!
