Double-check that you’ve got the defaultProtocol and inital_hosts set correctly. Also note Björn’s comment in this thread about setting java.net.preferIPv4Stack=true if you are on Linux.

I had already setup 2 Alfresco Enterprise 3.1 with trial license in 2 virtual machine and also set the log level of jgroups to INFO but i still can’t see the log message about join and leave node.

Am I miss something?

Thank you
Tommy

Sorry!

I have problem on install Alfresco community Edition -3.2r-Linux-x86 on RHEL 5.2 X64 and All the application is located on /opt/alfresco but the directory alf_data is located on NAS mounted directory (/data/ GFS) and
i have modified dir.root=/opt/alfresco/alf_data TO dir.root=/data/alfresco/alf_data

this is the catalina.out:

Thanks for help

* If you configure an Alfresco Cluster setup on Linux, be aware that multicast (UDP) does not work properly if you have IPv6. You should pass this flag to the JVM when starting Alfresco:

-Djava.net.preferIPv4Stack=true

This is not mentioned in the Alfresco documentation as far as I am aware, but is quite clearly noted on the JGroups website.

* Also be aware that the alfresco.tcp.initial_hosts is indeed a required property if using JGroups TCP protocol stack – also noted on the JGroups website.

Thanks for a good tutorial, as usual.

When you changed your props to point to the NAS-mounted directory, did you also move all of the files from /opt/alfresco/alf_data to /alf_data_cluster? Or are you starting with completely clean repository (clean data directory AND clean database)?

Also, make sure the account running Alfresco has full access to the directory (can create/delete files).

I have posted a message on Alfresco forum and ACT. I am experiencing a strange issue. If I pointed dir.root to a local directory (eg: dir.root=/opt/alfresco/alf_data), Alfresco started fine. However, after I changed dir.root to a mounted NAS storage (eg: dir.root=/alf_data_cluster) as part of configuring Alfresco clustering , Alfresco failed to start. The error msg I got is

2009-08-11 17:15:33,949 INFO [STDOUT] 17:15:33,949 User:System INFO [repo.admin.ConfigurationChecker] The Alfresco root data directory (’dir.root’) is: /alf_data_cluster

The alfresco UNIX user has RW to the mounted directory.

Have you seen this kind of error in the past?

Thanks for your time.

Also, you mentioned a “replicated” content store. In the setup I describe in this post, there is not a replicated content store. There is a single content store that both Alfresco nodes share.
