index out of disk space, CorruptIndexException

[Brian Whitman <br...@variogr.am>]

We had an index run out of disk space. Queries work fine but commits  
return

<h1>500 doc counts differ for segment _18lu: fieldsReader shows 104  
but segmentInfo shows 212

org.apache.lucene.index.CorruptIndexException: doc counts differ for  
segment _18lu: fieldsReader shows 104 but segmentInfo shows 212
	at  
org.apache.lucene.index.SegmentReader.initialize(SegmentReader.java:191)

I've made room, restarted resin, and now solr won't start. No useful  
messages in the startup, just a

[21:01:49.105] Could not start SOLR. Check solr/home property
[21:01:49.105] java.lang.NullPointerException
[21:01:49.105]  at  
org 
.apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java: 
100)

What can I do from here?

that message usually comes after some earlier (possibly much earlier) 
error about the real cause of the problem (usually with a meaninigful 
stack trace).  I'm guessing that the meaningful error in this case hwoever 
is something along the lines of "index corrupted" but it might have ust 
been a stray lock file.

thanks for the tip, i did run that, but I stopped it 30 minutes in, as  
it was still on the first (out of 46) segment.. The index is (was)  
129GB.
I just restored to an older index and made this ticket, https://issues.apache.org/jira/browse/SOLR-455

uggggg -- maybe someone else has better ideas, but you can try:
http://svn.apache.org/repos/asf/lucene/java/trunk/src/java/org/apache/lucene/index/CheckIndex.java

I think that converts (what it can) to a 2.3 index.

The NullPointerException should be gone in trunk, that is just an 
artifact of stuff going wrong during initialization.
