Answer 1

Alfresco store data on 2 different places, as it is document management system it is having 2 things to store.First one is files and folder and second one is metadata related to that.Files are stored inside the alf_data folder and metadata information are getting stored in database.Two different alfresco instance can not pont to different database and save dir root location

Now if this things are not synced in alfresco in that case it will give above error.

If you are setting up clustering environment you should refer below link.AFAIK , its only supported in enterprise edition.

http://docs.alfresco.com/5.0/concepts/ha-intro.html

Answer 2

Can you provide a bit more information as to: 1. When you say

I am installing Alfresco 5.2 on 2 linux node's on with same schema

Are you trying to setup two nodes in a cluster pointing to the same database? Also, is the 5.2 version enterprise or is it community edition? If it is community edition, I don't think clustering is supported as per Alfresco Versions comparison

2. The location that you are using

/mnt/data/alf_data

Is it a shared location across both the nodes? I am sure you must have verified this, but can you double check the permissions on the alf_data (it should be read/write enabled)

Answer 3

Stop server.

Create new database in DB and then change db.name=NEW_DATABASE_NAME in alfresco-global.properties.

Start server.
