Solr Index Failing To Build

[Scott Renton]

Hi folks,

This problem is on a 1.8 deployment. I've had a good look, and haven't managed to find this occuring anywhere else!

I'm quite familiar with the agreed process that, should running ./dspace update-discovery-index -f (or -b) fail, the simplest way to rebuild is to delete the [dspace]/solr/search/data folder, restart the site and run again.

I'm in a situation where the re-creation of the data folder (and indexes within) is not happening, and attempts at replacing with a similar index from a related server are similarly failing. The error is as below, and It does not seem to be a permissions issue.

I wonder if anyone is aware of any config beyond [dspace]/config/modules/discovery.cfg (currently set to search.server = http://localhost:8080/solr/search) and the solrconfig.xml in [dspace]/solr/search/conf (which has standard settings) which might affect this, or knows of any other reason why the update mightn't take place. 

Thanks very much,

Scott

Fixed- the solr indexes were building (somehow) under ...tomcat/bin/solr. Commenting out the dataDir line in solrconfig.xml fixed it, but no idea where solr.data.dir was being set to this anomalous directory.
