It's certainly possible to move a core like this. You say you moved the core. Did you move the core.properties file as well? And did it point to the _same_ directory as the original (dataDir property)? The whole purpose of write.lock is to keep two cores from being able to update the same index at the same time.
If you have a dataDir in the core.properties file _and_ it points to an absolute directory then this is proper behavior. And also look at the paths printed out. "/var/www/solr/data/prindex/data/index/" is where the write.lock file is. This implies that somehow you have two cores pointing to the same place. Of course I may be way off base here.... Oh, and I'd shut down the Solr instance before copying anyghing. Oh2, I'd have all my Solr instances shut down before copying anything. Oh3, _really_ examine the core.properties file(s) and be sure they have different names assigned to each core....
