Alfresco, Java and OCFS2 issues

vasillalov — Wed, 27 Feb 2008 22:20:01 GMT

All,I would like to report that Alfresco cannot be deployed on an OCFS2 volume. Aparently, there is a jar file in the tomcat library provided with Alfresco that attempts to perform low-level I/O. This causes an un-handled Java I/O exception and alfresco does not run.This is on RHEL5 with OCFS2 v. 1.

Hi

This error usually comes when there is a missing or wrong entry in a /etc/hosts. Have a look.

Thanks
Alexander

Hi there,

I don't think this is the case here. Alfresco installed and worked fine on ext3 volume.

The error says:

Cannot bind to URL [rmi://localhost:50500/alfresco/jmxrmi]‍

This means it can not establish TCP/IP (not file system) RMI connection.

I had similar error (and many on this forum too) and hosts file fixed it.

By hosts file you mean /etc/hosts, correct?

Yes, you are right.

Well,

The /etc/hosts has the correct information. The issue remains, alfresco works on an ext3 volume and crashes on OCFS2 volume. Same machine, same OS, same everything. The only change is the file system on that volume.

I did some further experimentation and it turns out that it is the lucene index that can't be placed on an OCFS2 volume. I am able to run alfresco from ext3 volume and the alf_data/contentstore folder relocated to an OCFS2 volume.

That way I can share the same content store between two servers and not worry about journaling problems and file locks.
