nfs problems
I have been having some strange nfs problems. Our main file server, filer, has several mounts exported, serving to ~15 users. No one has any problems, except 2. Recently their computers (1 is a clone of the other) their computers will lock-up when they are nfs mounted, but work fine when they aren't. All systems are Ubuntu x86_64 on dual opteron systems, nearly all are identical. The server does not have any error messages, nor do the workstations. Does anybody have any ideas?

First make sure you start portmap and nfs client services:
Code:
sudo /etc/init.d/portmap start sudo /etc/init.d/nfs-common start Code:
showmount -a showmount -d showmount -e Try to mount NFS directory with intr option, so if it hangs you can press CTRL+C: Code:
mount -o hard, intr nfsserver:/path/to/dir /local/mnt Code:
mount -o soft,timeo=10 nfsserver:/path/to/dir /local/mnt Code:
mount -o hard,intr, nfsvers=3 nfsserver:/path/to/dir /local/mnt Also on nfs sever run command: Code:
tail -f /var/log/message Try out all these troubleshooting tips and let us know ..

I think it is fixed
Portmap was originally set to look at 127.0.0.1. I changed it to the eth0 address, and the problem remained. nis at this point was also not working, rpcinfo -p was not giving out info, unless you either specified loopback, or the hostname. Changed portmap to listen to both sides, nis started working, and so has nfs, the computer hasn't crashed since.
Thanks for your help!
