Hi Susheel, Thanks for the reply. I'm not entirely sure what you mean.
When I created the new directory on the new volume I simply created an empty directory. I see from the existing data node directory that it has a sub-directory called current containing a file called VERSION. Your advice is to create the 'current' sub-directory and copy the VERSION file across to it without changes? I see it has various guids, and so I'm worried about it clashing with the VERSION file in the other data directory.
