NFS fails to start

[Kenneth Lundström]

Hello LTSP users,

a couple of months before Christmas I installed a couple of LTSP
servers. One was commissioned before Christmas and is working great. The
second I delivered to another place a couple of weeks ago, finally. This
site already have one LTSP from before and I was planing on replacing
it. Using it as an fileserver for homes folders.

I setup it up and clients find it and they work. Then I proceed to mount
the home folder via NFS and get them mounted. I leave the place and next
they I get an call that they can't login anymore. I try to find the
error via SSH but can't. So I switch back to using the old server again.

Now I come so far that I know that NFS doesn't start for some strange
reason. If I do a /etc/init.d/nfs restart I get an error saying:

exportfs: /opt/ltsp does not support NFS export

I tried googling it but couldn't find anything that would work for me.

Any ideas where to start searching. I think it has something to do with
me setting up the homes folder mounting.

please publish the /etc/exports file on the broken server as well as the
output of getenforce

OK. Look in /etc/sysconfig/nfs and see what version of NFS is being used.
If NFSv4 is on, your /etc/exports is wrong. Change settings to use NFSv3 in
that location and restart nfs.

Hi,

when I look at the /etc/sysconfig/nfs all rows are commented out.

Any other way of finding out what version is in use?

Hi,

changed and no change :=) I even rebooted the server but no luck. The
strange thing is that NFS is not set to be automatically started. So I
guess something I have installed on the server has turned of NFS and
somehow makes NFS not to work.

I even tried to compare with the other working server but no luck.

Hmmm, I'm running CentOS 6.4 on the server. I thought I was using 6.3
but maybe one thing I did at some stage was a yum upgrade. The other
server is running 6.3. Could this maybe be the problem?

Client boot on Scientific.

OK. time to pull a final test run before I pull out my hair.

Open two terminal sessions on the server

on terminal one run:
setenforce 0
tail -f /var/log/messages /var/log/secure

on terminal 2 run:
echo "BEGIN TEST HERE" >> /var/log/messages
service nfs stop
service nfs start
exportfs
nfsstat

Once you run the echo on terminal2 you should see the tail update. post
what you see back here after the echo, please as well and anything from the
later commands (especially the nfsstat).

Hmmm, I'm running CentOS 6.4 on the server. I thought I was using 6.3
but maybe one thing I did at some stage was a yum upgrade. The other server
is running 6.3. Could this maybe be the problem?
Client boot on Scientific.
Kenneth
Hmm. what version OS are you running? CentOS/ScientificLinux/RHEL 5 or 6?
'chkconfig nfs on' will run nfs at bootup.

Hi,
changed and no change :=) I even rebooted the server but no luck. The
strange thing is that NFS is not set to be automatically started. So I
guess something I have installed on the server has turned of NFS and
somehow makes NFS not to work.
I even tried to compare with the other working server but no luck.

Hi,
when I look at the /etc/sysconfig/nfs all rows are commented out.
Any other way of finding out what version is in use?
Kenneth
OK. Look in /etc/sysconfig/nfs and see what version of NFS is being
used. If NFSv4 is on, your /etc/exports is wrong. Change settings to use
NFSv3 in that location and restart nfs.

Hello LTSP users,
a couple of months before Christmas I installed a couple of LTSP
servers. One was commissioned before Christmas and is working great. The
second I delivered to another place a couple of weeks ago, finally. This
site already have one LTSP from before and I was planing on replacing it.
Using it as an fileserver for homes folders.
I setup it up and clients find it and they work. Then I proceed to
mount the home folder via NFS and get them mounted. I leave the place and
next they I get an call that they can't login anymore. I try to find the
error via SSH but can't. So I switch back to using the old server again.
Now I come so far that I know that NFS doesn't start for some strange
exportfs: /opt/ltsp does not support NFS export
I tried googling it but couldn't find anything that would work for me.
Any ideas where to start searching. I think it has something to do
with me setting up the homes folder mounting.
Kenneth

I think you might be looking in the wrong place. An ltsp server exports NFS to the thin clients so they can boot their OS. If you want to export /home from your old server, you will need to set it up and make sure the new server is mounting it. To me it looks like you aren't even exporting /home. If you want to authenticate from the old server as well (so you won't have to add all your users to the new system again, you need to have it using NIS or LDAP or samba, and set the new server to authenticate users from there, assuming they aren't local (to the server) users (like root).

Hi,

the problem is not the /home folders, that works fine. The /etc/exports
I have shown is on the new server, the clients can't mount the /opt/ltsp
and can't boot at all, anymore.

check contents of /etc/auto.misc for /opt/ltsp. Comment it out if found

In fact do a:

grep -R ltsp /etc/*

and see where ltsp is referenced.

Also do a

lsmod | grep nfs

and make sure the you get something like:
nfsd 274672 13
auth_rpcgss 48594 1 nfsd
nfs_acl 12741 1 nfsd
lockd 93540 1 nfsd
sunrpc 256499 29 nfsd,auth_rpcgss,lockd,nfs_acl


If no nfsd, then BINGO! Just run modprobe nfsd and service nfsd restart

and see where ltsp is referenced.
Also do a
nfsd 274672 13
auth_rpcgss 48594 1 nfsd
nfs_acl 12741 1 nfsd
lockd 93540 1 nfsd
sunrpc 256499 29 nfsd,auth_rpcgss,lockd,nfs_acl
If no nfsd, then BINGO! Just run modprobe nfsd and service nfsd restart

[Jim Kinney]

Totally strange.

I saw a blurb on a Ubuntu page where there was a kernel bug related to ext4
filesystem shared out by NFS. However, even though it showed the same
error, it was still mountable from a remote machine.

I have a vanilla CentOS 6.4 with kernel 2.6.32-358 I tested the NFS server
on with no issues.

/etc/exports:
/home *(rw,no_root_squash,async)

disables NFSv4 in /etc/sysconfig/nfs

turned off iptables for the test

actually have selinux in enforcing mode

mounted remotely with no issues or errors on starting nfs service.

At this point, I think there's a problem with the hard drive. The top level
inode collections are screwed up and NFS can't "do it's thing" because it
can't read the filesystem metadata.

I would run 'badblocks' on the drive and reinstall (lousy answer and bad
sysadmin solution but short of running strace on everything it may be the
fastest way to working) with a fresh drive format.

Hi,
I also tried to mount /opt/ltsp shared on the new server on the old
server, just to test the share, so doing
mount -t nfs 192.168.0.1:/opt/ltsp /mnt/test/
May 2 07:37:00 ltsp rpc.mountd[2186]: authenticated mount request from
192.168.0.11:978 for /opt/ltsp (/opt/ltsp)

(Invalid argument)
May 2 07:37:00 ltsp rpc.mountd[2186]: qword_eol: fflush failed: errno 2
(No such file or directory)
May 2 07:37:00 ltsp rpc.mountd[2186]: Cannot export /opt/ltsp, possibly

Post by Jim Kinney
check contents of /etc/auto.misc for /opt/ltsp. Comment it out if found

don't have any files called /etc/auto.misc

Post by Jim Kinney
lsmod | grep nfs

nfsd 304962 11
lockd 73534 1 nfsd

auth_rpcgss 44917 1 nfsd

sunrpc 261299 17 nfsd,lockd,nfs_acl,auth_rpcgss
Looks to me OK?

and see where ltsp is referenced.
Also do a
nfsd 274672 13
auth_rpcgss 48594 1 nfsd
nfs_acl 12741 1 nfsd
lockd 93540 1 nfsd
sunrpc 256499 29 nfsd,auth_rpcgss,lockd,nfs_acl
If no nfsd, then BINGO! Just run modprobe nfsd and service nfsd restart

Hi,

sounds like an Windows fix, please reinstall :=) But that is just what I
decided needs to be done, I emailed the client and will head out to
client tomorrow morning.

One strange thing I noticed by mistake is the dates on folders.

[***@ltsp tmp]# ll /opt/
total 4
drwxr-xr-x. 5 root root 4096 Mar 17 1913 ltsp

LTSP was hardly thought of 1913. I tried to look in different logs but
can't see any file errors. But I see some folders being dated to 1913.
Should matter for NFS, but if filesystem is that messed up no wonder NFS
doesn't work.

Totally strange.
I saw a blurb on a Ubuntu page where there was a kernel bug related to
ext4 filesystem shared out by NFS. However, even though it showed the
same error, it was still mountable from a remote machine.
I have a vanilla CentOS 6.4 with kernel 2.6.32-358 I tested the NFS
server on with no issues.
/home *(rw,no_root_squash,async)
disables NFSv4 in /etc/sysconfig/nfs
turned off iptables for the test
actually have selinux in enforcing mode
mounted remotely with no issues or errors on starting nfs service.
At this point, I think there's a problem with the hard drive. The top
level inode collections are screwed up and NFS can't "do it's thing"
because it can't read the filesystem metadata.
I would run 'badblocks' on the drive and reinstall (lousy answer and
bad sysadmin solution but short of running strace on everything it may
be the fastest way to working) with a fresh drive format.

[Jim Kinney]

That date error is very suspicious.
Yeah, windowsish solution indeed :-(
Run memtest before the install as a flaky dimm can cause these errors as
well.

Hello,

finally got a chance to reinstall the whole server, I have no done it
twice, last thing was to use ext3 instead of ext4 (just a wild guess).
But I still the same error.

I guess I need to change the whole server. But this has worked, I just
can't understand what the problem is.
