NFS server connection issue.

driliter · October 3, 2014, 9:08pm

I’ve been using opensuse for many years and have decided to set up a central file server for all of the computers in our home using 13.1. I can ssh into it instantly. I have worked through the opensuse nfs server how to but I cannot get my client to see the server even with the firewall down. I have set up a static IP address on the client and server all going through a cisco gigabit switch as well as adding the host and client to the respective hosts files. I’m also using 2 x 2gb hard drives in a raid 0 configuration for /srv and a small (30gb) ssd for /. I have nfsv4 enabled on the server but neither a v3 or v4 will mount on the client.

when I run showmount -e 192.168.1.2 on the client it takes some time but I get

linux-86pk:/home/andy # showmount -e 192.168.1.2

All mount points on linux-ulh0:

It will not work trying to mount through Yast, fstab or a manual mount using “mount -t nfs 192.168.1.2:/srv /home/andy/.mnt” which just times out with no entries on /var/log/messages about nfs.

.

I’ve trawled the internet and various man pages but can’t figure out for the life of me what I’m doing wrong! Any help gratefully received!

Thanks.
Andy.

What’s your firewall configuration? Try disabling the firewall and see
if the mount works then.

If it doesn’t, look at the output in /var/log/messages and see what
messages are recorded on the server.

Both firewalls?

Do you see something like this on the server?

The first thing to try is mounting something on the server, via nfs. Not on the client.
That way you clear out configuration errors before dealing with network problems.

Hi Thanks for the replies. I’ve turned off both firewalls. When I runsystemctl status nfsserver.service on the server I get:

I tried briefly with freenas before coming back to suse with exactly the same result. Making me think it’s a client error and not a server one.

/var/log/messages is empty on the server.

Thanks.

That’s not normal. There should be something in it. Make sure you
look as root, you won’t see anything at all if you try as a user (though
you should get a permission error doing that).

Nope, completely empty. I’ve ssh’d in, used su, opened the ncurses yast2 gone to miscelaneous and system log, completely empty. I tried cat, grep for any nfs entries and looking at it with vi, still empty. Could it be something to do with the switch? Seems odd that I can ssh in to the server fine though. I also don’t understand why showmount -e 192.168.1.2 run on the client (192.168.1.3) shows the list of shares from the server (eventually, takes some time) but I seem unable to mount them in any way. I’ve recently reinstalled the server and started from scratch, no change. Next step is to reinstall the client opensuse just in case there’s some weird setting that I’ve not noticed but I’m reluctant to do that unless I have to, and I’m not convinced it’ll make a difference at this point…

driliter · October 4, 2014, 5:35am

actually when I go into /var/log and ls all I get is

alternatives.log btmp faillog krb5 lastlog ntp pbl.log wtmp YaST2 zypp zypper.log

Miuku · October 4, 2014, 9:22am

If you used minimal server installation, there is no syslog installed by default (which is pretty crazy if you ask me).

zypper in -y rsyslog
systemctl start syslog
systemctl enable syslog

Then reboot the system just to make sure all services log properly.

driliter · October 4, 2014, 11:44am

Yup, that was it. A very minimal server just bare bones and then nfs server installed on top. Did the above and what I have after attempting mount -t nfs 192.168.1.2:/srv /home/andy/.mnt is:

Stood out for more research :-).

Ok I think I may be getting somewhere! After rereading an above post I tried to mount a server share on /home/andy on the server. the shares showed up in yast2 ncurses when I did this.

when I cd into /home/andy/mnt and ls, the directory is populated. Everything is there!! Must be a network problem.

Thanks for your help.
Andy

Problem solved. After the best part of 24 hours straight going round in circles, connected the computers together directly, worked perfectly… It’s the switch (cisco SG 200-08)!!! (Rant alert!)

For some reason cisco thought it would be a great idea to drop SYN packets from the privileged ports, the ones NFS uses. DOS control, which can’t be switched off. Not sure if it’s a problem with all cisco switches but this one definitely.Tried to upgrade the firmware to see if they fixed it and the wonderful little thing is bricked. Won’t be buying cisco again.

Just bought a cheap netgear one… everything shows and works perfectly!

There’s a lesson in here somewhere if I could only just see it…

Wow.

Google around… perhaps it can be “unbricked”. :-?

Quite…

I did suspect the switch at your first post. Just the sniff of s
suspicion. Like “that’s a complex thing. What if it is the switch? But I
know very little about those things. Nay… it won’t be that.”

A complex, /good/ switch does clever things. Cheap ones are transparent.
Sigh.
Yes, a lesson for us all…
