NFS Server on Linux : How exactly ?

deas0815

Hallo,

I'm trying to get the NFS Server to work on linux and I have read
http://wiki.alfresco.com/wiki/File_Server_Configuration#NFS_Server_Configuration.

I'm not an expert here but the situation is the following:

The alfresco NFS Server is configured in file-servers-custom.xml:

   <config evaluator="string-compare" condition="NFS Server">
          <serverEnable enabled="true"/>
<MountServerPort>1678</MountServerPort>
<NFSServerPort>12049</NFSServerPort>
<rpcAuthenticator>
  <userMappings>
    <user name="admin" uid="0" gid="0"/>
  </userMappings>
</rpcAuthenticator>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍

and it seems to be up:

[root@oscar ~]# netstat -anp | egrep -i "(12049.*LISTEN)|(1678.*LISTEN)|(111.*LISTEN)"
tcp        0      0 :::1678                     :::*                        LISTEN      21332/java
tcp        0      0 :::111                      :::*                        LISTEN      1785/rpcbind
tcp        0      0 :::12049                    :::*                        LISTEN      21332/java
[root@oscar ~]#  ‍‍‍‍‍

The native nfs services (rpc.*d) are running on this system as well, that is why
I've configured the alfresco NFS server to run on special ports.

The problem now is that I cannot mount the alfresco exports:

[root@oscar ~]# mount -o mountport=1678,port=12049 localhost:/ /mnt
mount: mount to NFS server 'localhost' failed: RPC Error: Success.
[root@oscar ~]#    ‍‍‍

What am I missing ?

Any help is appreciated.

regards
Andreas

After setting up in the same manner, I got the following, so not much help here.

mount to NFS server 'localhost' failed: server is down.

In case you never got this to work or someone else is interested, I used the following config in the file-servers.xml to mount the alfresco file system on a solaris client:

   <config evaluator="string-compare" condition="NFS Server">
          <serverEnable enabled="true"/>
          <enablePortMapper/>
          <MountServerPort>1678</MountServerPort>
          <NFSServerPort>2049</NFSServerPort>
          <rpcAuthenticator>
            <userMappings>
              <user name="admin" uid="0" gid="0"/>
            </userMappings>
          </rpcAuthenticator>
   </config>

# mount xx.xx.xx.xx:/Alfresco /mnt/alfresco

I couldn't deviate much with the ports since mount on solaris doesn't seem to support all of the flags you used, but I did connect nonetheless.

Hi,

I have been facing the problem in the client side while I try to access the alfresco file system through the NFS protocol from another Solaris machine in the same LAN.
# /etc/init.d/nfs.client start
nfs mount: mount: /export/home/clipper/alfrescoDafadilfo: I/O error

System Details:
Alfresco Server is running in the tomcat server V6.0.0.18 in the solaris machine.
Client is another solaris machine within the same network.

The various configurations in the client and the server are given below:
Alfresco Side Configurations:
[size=85]FILE-SERVERS.XML CONFIGURATION
<config evaluator="string-compare" condition="NFS Server">
<serverEnable enabled="true"/>

<NFSServerPort>2049</NFSServerPort>
<rpcAuthenticator>
<userMappings>
<user name="admin" uid="0" gid="1"/>
</userMappings>
</rpcAuthenticator>
</config>[/size]

When we restart the client machine, there is no error noticed in the alfresco log in the tomcat server. But unfortunately we are getting I/O Error in the client machine as given above.

Any help would be appreciated.

I know this post is old, but for anyone else that might encounter this - there is a note on the wiki that indicates the uid and gid can't be different due to an NFS bug.
