This issue is for documentation.

I encounter error messages in the watchdog after a server was rebooted:

Can't obtain shared reading index lock Error thrown in /path/to/drupal/sites/all/modules/luceneapi/contrib/luceneapi_node/luceneapi_node.module on line 448.

Can't obtain shared reading index lock Error thrown in /path/to/drupal/sites/all/modules/luceneapi_morelikethis/luceneapi_morelikethis.module on line 362.

Search Lucene worked fine during many weeks. Now these modules don't work anymore:
Search Lucene API
Search Lucene MoreLikeThis
Search Lucene DidYouMean

We use NFS and as per the documentation here, NFS is not supported:
http://zendframework.com/manual/en/zend.search.lucene.index-creation.html

This issue helped me to find out the "Supported Filesystems":
#837616: Fatal error on index

In this case the statd and idmapd daemons were not started and caused the errors. The module works again after starting them.
