nfs server is not responding
Last modified: 2007-04-18 12:44:19 EDT
Description of Problem:
it fails accessing on the nfs client (7.3+updates) the mounted nfs shares from
the server (limbo)
A simple ls on the directory causes the message nfs server 192.168.10.12 is not
Version-Release number of selected component (if applicable):
export the shares via /etc/exports (including the async option didn't resolve
Steps to Reproduce:
1. mount the nfs share from the limbo-server
2. receiving a prompt
3. a ls on the directory brings up the message nfs server 192.168.10.12 is not
4. both systems couldn't be rebooted (couldn't kill the processes)
Can you try nfs-utils-1.0.1-0?
I tried it with nfs-utils-1.0.1-1, but the result is still the same. I don't
receive the message any longer, but the connection hangs and I can't access to
the share. When I try to shutdown the server - the system hangs.
This is pretty ugly Bob. Suggest you rope in additional assistance.
Please attach nsfd, mountd and statd messages from the server logs. Also, I'd
be very interested to know what network card is installed on the server.
When you say that the server can't be rebooted because it couldn't kill the
processes, what do you mean? Does it hang on shutdown? If so, what messages
are generated? Can you kill the processes by hand with kill(1)?
I recreated this setup (Limbo server with kernel-2.4.18-5.74, nfs-utils-1.0.1)
and 7.3 client. I did not have any problem mounting, reading or writing to NFS
directories on the client. The machine also reboots cleanly.
Also, why are you trying to NFS mount 192.168.10.12 =
I hate to reopen a wound here, but I'm seeing the exact behavior joachim
described. This may (or may not) be related to the issues in bugs #70069 and
#70321. In my case I have a limbo2 system with all updates as the server, and a
valhalla system with (I think) all updates as the client.
The server has the following components:
The server has a D-Link DE-570T NIC, and the client has a Netgear FA310TX. I'll
attach a file with sample configs and log messages.
What's really odd is that the file system gets hung on the server as well. I
ran a "watch ls -la" on the exported FS on the server, and it hung a few seconds
after the mount. I'll include some ps output in the attachment.
I'm going to keep poking at this problem. I'll add in any useful information I
Created attachment 71224 [details]
Sample commands and log/ps output
On the server, it seems to only affect the portion of the FS that was NFS
mounted. eg, on dynamic229 all of /home was exported. After the mount I can
still descend into /home, /home/warehouse, etc. As soon as I touch
/home/landfill, though, my "ls" goes into state D.
An attempt to reboot the server produces:
Shutting down NFS daemon: [FAILED]
and an indefinate hang at
Shutting down NFS services:
The system is already trying to shut down, so it's impossible to resolve this
with anything other than a hard reset.
Installing the updated kernel from 7.3 (2.4.18-5) on the limbo system seems
to make things work. I guess this is a kernel issue after all.
after the setup of the beta on another machine (completely different hw) it
works quite well there.
So I've also setup the first machine from scratch with kernel 2.4.18-10.99 and
now the server-functionality also works well.
I just installed the latest beta (7.3.94, (null), kernel 2.4.18-11) on the
beta box (server), and all appears happy. I've got my tunes playing right now,
and I'll chuck some ISOs back and forth just to be sure.
