Our storage server threw it's toys of the pram. We got it back, and everything bar ElasticSearch is singing sweetly again.
On start, we get an IndexFormatTooNewException. Not many get that one, but CheckIndex appears to be worth a go, except that also barfs: nicks@elasticsearch:/var/lib/elasticsearch/elasticsearch/nodes/0/indices/support/3/index$ sudo java -cp /usr/share/elasticsearch/lib/lucene-core-4.8.1.jar -ea:org.apache.lucene... org.apache.lucene.index.CheckIndex . -fix Opening index @ .

Any suggestions to fix it would be appreciated, we are uncertain how to proceed otherwise. ES 1.2.1 from Debian packages. We are just (now) upgrading to 1.4 to see if this results in some progress.
