nfs mounting problems.

I have read nearly every thread I could find, searched, and read the NFS how-to to get NFS working, all with no luck so far. I'm at my wits end.

Two machines, same private network. From the client I can do an 'rpcinfo -p server', and I get the list of rpc services indicating NFS is running and accessable by the client.

got the same problem.
I m connecting with my gentoo box to an debian-nfs server.
My flatmates are able to mount without problems.
It s only my box where all applications accessing the mounted files crash unkillable.
iOnly tabcompleting in the mounted directorys smashes the bash :)
sometimes I can browse the files using xmms, but the player also doesnt respond anymore when triing to play them or earlier:

dont know too much bout reiserfs, but I know for sure the server is working,
Also I have a user with same uid as the owner of the nfs files on the server,
portmap running and nfs suppert for nfs the kernel.

I just realized I dont have nfs-utils installed
will give it a trie :)

no changes with nfs-utils.
I mounted without prolems, I browsed with console everything worked fine.
I tried aplay on one of the mp3
and the console crashed.
dmesg outpu:

In followup to this.. the client kernel log has this:

Feb 11 10:09:20 [kernel] nfs: server gentoo not responding, still trying

I figured out this could have something todo with the order in which nfsd portmapper or nfsmount are started, triing to ind more about this ...

I've had this problem as well. Attempting to mount an nfs share would hang the system. After checking dmesg, I found an error saying that "NFSv3 not supported." Turns out I had forgotten to enable this when compiling the kernel. Check in File Systems --> Network File Systems and make sure you have support for Version 3 enabled.

I've got it now. I forgot I had to do this as well:

rc-update add portmap default

reboot, or start portmap from /etc/init.d\

Your nfs should mount instantly afterwards.

hmm, I offcourse addet portmap to the runlevel, doesnt change much, also tried in different starting it after after the boot.

here comes the strange thing. My laptop connected to the nfs server via the same hub, has the same problems.
I just installed it fresh with gentoo-2004-stage.

also connected to this server but not over the hub are another gentoo laptop and a debian computer.

I got no idea what todo bout this and nfs should be soo easy

The only other thing I changed when I set up my NFS was to add the insecure option to /etc/exports on the server. This makes the server allow connections on ports above 1024. I'm not sure if this would help or not, but it might be worth a try. My exports file looks like this:

/usr/local/nfsshare client(rw,insecure,sync)

Other than that, I'm out of ideas. Sorry I couldn't be more help.

actually the server is prettty strict there

# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
/home/media/musik 192.168.1.*(ro)
/tmp/musik 192.168.1.*(ro)
/home/media/video 192.168.1.*(ro)

but its not mine :)

I have the same problem.
I can share to my second computer without problems....
play movies from my main computer and what not.
But when i do the same thing with my second computer
(using my main computer as client) i get this:

nfs: server 192.168.10.20 not responding, still trying
nfs: server 192.168.10.20 OK

and sometimes this:

nfs warning: mount version older than kernel

portmap is on, mounting is not a problem. but performance
becomes miserable.

i dont have a clue how to figure this out..

Do you have portmap running on the clientside?

overdozed · Posted: Tue Feb 17, 2004 6:19 pm Post subject:

I have portmap running everywhere.
I finally think its something with the user, or another permission thingy, hmm ...

I decidet to forgett about nfs and am now mounting via sshfs(lufs rox :)

Are you sure you really werent unable to mount? i get that freeze too, but if i wait _exactly_ 5½minutes, the mount is finished & works fine - it seems to be some timeout somewhere.. and its annoying:/

In your case I d say the portmapper isnt started,
sometimes I also wait 5 min untill it loads and then can make my apps crash :)

Thulle · n00b Joined: 11 Nov 2002 Posts: 70

ah, you have to start it on the client too.. works fine now;)

I do have the same problem as Trekkie. Mounting and main directory listing is fine, but no way to actually access any files or cd into subdirs.
Good to know I'm not the only one though.

well after some testings here on my systems I'm really confused......

cause if I start tcpdump -i eth0 'port !ssh' on by Local Server to watch the traffic, my NFS works.. its really slow and I can see some timeouts but I get some data.....

if I terminate tcpdump again its all the same again !!

I have a very similar problem to some of you.

When I do mount -t nfs server:/file /mountpoint
the particular bash that I type it into hangs. Ctrl-C Ctrl-Z and kill -9 ing the mount do nothing. However, if I kill -9 a process called rpciod then mount will stop being hung and the bash prompt returns. Odd eh?

It works fine after this.

I am using gentoo-gnu-linux_standard sources on both PCs.

All I can say is install and run portmap on both server and client and use 192.168.1.43:/nfshome style rather than myserver:/nfshome because then it works.
