NFS mount fails "reason by server: No such file or directory" , but dir exists!

[thrombomodulin]

Hello,

On Fedora 7, I attempted to setup NFS4 between two hosts which didn't work. So, I tried to use NFS with server and client on the same host. I followed the instructions at this address quite exactly.

http://wiki.linux-nfs.org/wiki/index.php/Nfsv4_configuration

I suspect the example mount command given there might have left off ":/export", so I tried it both ways. Regardless, the same error always occurs. Thanks in advance for any help.

Regards,
Pete

P.S. SELinux is in permissive mode.

I think /etc/exports must contain something like:

/export 127.0.0.1(ro) 192.168.1.2(ro) 192.168.1.3(ro)

I think my /etc/exports file is identical already to what you suggest I should change it to. Thanks, Pete

Hi thrombomodulin,

I am too facing the same problem.

found the following link suggesting a solution, however my initial attempts to configure it is failed.
I am still searching for the cause and solutions.

What does "exportfs" report is shared ?

Prabhat3107,

I found this links also. I followed the instructions exactly. NFS4 now works between my two Fedora 7 machines.

Hi,
I could suceed in configuring nfsv4 server.

the importent thing with nfsv4 server is you need to put fsid=0 option with the exports.
for example: (in /etc/exports)
/home/data *(ro,fsid=0)

if you do not use fsid=0 option you will get the
"mount.nfs4: 127.0.0.1:/export failed, reason given by server: No such file or directory "
error

refer the manual page
# man 5 exports

which say that
The value 0 has a special meaning when use with NFSv4. NFSv4
has a concept of a root of the overall exported filesystem. The
export point exported with fsid=0 will be used as this root.



If I have to make a correction in the /etc/exports file you have posted it would be as bellow
[root@homepc ~]# cat /etc/exports
/export 127.0.0.1(ro,fsid=0) 192.168.1.2(ro,fsid=0) 192.168.1.3(ro,fsid=0)

and while mounting the nfs share observer the folliwing

# mount -t nfs4 <serverip>:/ /mount/point

not mount -t nfs4 <serverip>:/exports /mount/point
