nfs zero byte file problem

flados

:? Hi,

I've installed Alfresco Enterprise 3.1 Release on a rhel4 and configured the alfresco nfs server.

The section in the file-servers.xml is this:
<config evaluator="string-compare" condition="NFS Server">
      <serverEnable enabled="${nfs.enabled}"/>
      <PortMapperPort>111</PortMapperPort>
      <MountServerPort>1678</MountServerPort>
      <NFSServerPort>12049</NFSServerPort>
      <!– Map NFS user/group ids to Alfresco users –>
      <rpcAuthenticator>
         <userMappings>
            <user name="admin" uid="0" gid="0"/>
         </userMappings>
      </rpcAuthenticator>
</config>

I've created a folder in /home/alfresco and mount the nfs path with this command: mount -t nfs <myalfrescoservername>:/alfresco /home/alfresco
After this i can browse correctly the folder of alfresco under /home/alfresco, but if I try to copy some files, or create new file, this are created with zero byte.

There's someone that can help me ?
Thank you very much for your support.
bye, Flavio

flados:

Can you enable debug logging as specified on the wiki?

I enabled debugging and am getting the following exception:

Exception in thread "NFSFileExpiry_167772493" net.sf.acegisecurity.AuthenticationCredentialsNotFoundException: A valid SecureContext was not provided in the RequestContext
        at net.sf.acegisecurity.intercept.AbstractSecurityInterceptor.credentialsNotFound(AbstractSecurityInterceptor.java:477)

        at net.sf.acegisecurity.intercept.method.aopalliance.MethodSecurityInterceptor.invoke(MethodSecurityInterceptor.java:77)
.
.
.

Anyone know what is causing this?

Hi,

I've enabled the debug with this options : <debug flags="RxData,Search,Info,File,FileIO,Error,Directory,Timing,Session"/>.

After I've unmount and re-mount : mount -t nfs <myalfrescoservername>:/alfresco /home/alfresco

If I try to copy a file (alfresco.log for example) with this command : cp /opt/Alfresco/Alfresco.lg /home/alfresco/Provvigioni/Alfresco.log apparently the file is copied, but with 0 byte lenght.

The trace of the log in alfresco.log is this (note the write response underlained):

Anyway thanks for your supporto.

Any update on this problem?

Has anybody the Alfresco NFS Server running correctly?

bmarbury

Nope, no replies yet.

Didn't have time to dive into the code so ended up using a CIFS mount (on RHEL5).

Example:

mount -t cifs //myserver/Alfresco /mnt/alfresco -o username=admin‍

Hi,

I have this zero byte file problem after enable and configure Alfresco NFS server.
I am using Alfresco Community 3.3 version running on ubuntu 8.10 and mounting
nfs share with this command as root:
mount -t nfs 127.0.0.1:/alfresco /mnt/alfresco/

Often the first few copied file is ok. But after a file's size is become 0
all others copied after that will have zero size.

Does anyone had similar problem with nfs server and managed to solve it?

This is my NFS config section on file-servers.properties:
### NFS Server Configuration ###
nfs.enabled=true
# Mount/NFS server ports, 0 will allocate next available port
nfs.mountServerPort=2999
nfs.nfsServerPort=2998

# RPC registration port, 0 will allocate next available port
# Some portmapper/rpcbind services require a privileged port to be used
nfs.rpcRegisterPort=0

# To disable NFS and mount server registering with a portmapper set nfs.portMapperPort to -1
nfs.portMapperPort=111
# Enable the builtin portmapper service
nfs.portMapperEnabled=true

# NFS session debug flags (also enable org.alfresco.fileserver=debug logging level)
# Comma delimeted list of levels :-
# RXDATA, TXDATA, DUMPDATA, SEARCH, INFO, FILE, FILEIO, ERROR, TIMING, DIRECTORY, SESSION
nfs.sessionDebug=FILEIO, ERROR, SESSION

nfs.mountServerDebug=true

Thanks
