NFS mount hangs

guarriman · 12-13-2006, 03:27 AM

Hi.

Working with Fedora Core 6 on server and Ubuntu 6.0.6 on client, I want
to mount --via NFS-- a directory on the client from the server.

I try:
mount -o nfsvers=2 myserver:/home/foo /home/user/myserver-foo -o nfsvers=2

But it hangs 120 seconds before mounting it, and it's not very comfortable.

Does anyone know what it's happening?

I stopped iptables on server and with FC2 as client it works ok.

Thank you very much.

I don't know about nfsvers=2 but, it could also be that using a name instead of ip address is where the delay comes from.
This is the command I use...
mount -t nfs -o ro 192.168.0.1:/mnt/backup/fedora /mnt/local

What does (and how fast) rpcinfo -p myserver say?

Then NFS mount should be as fast...

See if the versions are matching (a wild guess), and take out nfsvers=2 option.
