SolrCore 'logicaldoc' is not available due to init failure

[orschust]

Hello Community,

after days of searching and trying I hope someone of you can help me.

Current version: 7.1.3 CE with mysql
CentOS 6.5
Apache 2.2.15

I recently moved my LD CE installation from one server to another.
Everything works fine except indexing of documents. When I click on "Search and Indexing" I get the error
"SolrCore 'logicaldoc' is not available due to init failure: Could not load core configuration for core logicaldoc"
First thing I did is comparing hardly any file with the old installation but could not find any differences.

The logfile DMS.log in the data/log directory shows the following errors (just extracts):

"14.03.2015 08:27:19,078 ERROR (com.logicaldoc.web.service.SearchEngineServiceImpl: 92) -- SolrCore 'logicaldoc' is not available due to init failure: Could not load core configuration for core logicaldoc

Unfortunately it's not allowed to upload txt or log-Files - so please ask me, if you need the entire log file.

I'd appreciate any help. Please forgive me if I forgot relevant information. Just ask me if something is missing.

Thanks in advance,

Oliver

This kind of warnings are due to small Solr bug, you can disregard them

Unfortunately not - the indexing of documents is not working any more.

[mmeschieri]

Restart LogicalDOC, then enter in Administration->Settings->Search and Indexing. Here check the index path and verify it exists and contain files in the filesystem.

[orschust]

Thanks again for the reply. Just one problem.
There's a popup window with the error message
"SolrCore 'logicaldoc' is not available due to init failure: Could not load core configuration for core logicaldoc"
when trying to open the settings you described. I do not even get into the settings of "Search and indexing".

My guess is that it is an issue with a path or a permission. Where does LD look for the "core configuration"?

Any other suggestion where to start the search?

[mmeschieri]

You can find all index data into repository/index/logicaldoc

[orschust]

The question is: Does logicaldoc know this either?

In which config file does logicaldoc look for this information and how has this file to be configured?

I have a solr.xml in /logicaldoc/data/index. (/logicaldoc/data is the repo).

The content is:

<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="false">
<cores defaultCoreName="logicaldoc">
<core name="logicaldoc" instanceDir="." />
</cores>
</solr>

There is a subfolder /logicaldoc/data/index/logicaldoc with just a core.properties file and another subfolder called "conf" with
protwords.txt
schema.xml
solrconfig.xml
synonyms.txt

That's all.

The data folder is in /logicaldoc/index/data (not in the /logicaldoc/data/index/logicaldoc folder).
Could that be the problem and what to change if that is the problem.

I appreciate your help.

[mmeschieri]

Look at the image for the correct folders tree. The files you have to check are solrconfig.xml primarily and then schema.xml

[orschust]

Ecxept the base folder of the repo (in my case /logicaldoc/data) the structure is the same. I didn't change the xml files and can't find any error.
So I post the entire error message and hope this will help:

I compared the folder tree of the old installation to the new one. And there is a difference.
Even if I delete this new folder it will be created again when I restart logicaldoc. May this be a hint?
I am talking about the subfolder "logicaldoc" inside the folder "index".
