• Empty index?

Thanks!!!

Hi, have not seen this before. But can you look in /var/solr-6.6.0/shard2/solr/cese/data/index.20171103115319432 and see if that index is completely empty? The path looks funny, could it be some stale index from an auto snapshot or something?

Did you have any luck in upgrading your index?
