Hello, We have migrated from Solr 5.4.1 to Solr 6.4.0 and the disk usage has increased. We found hundreds of references to deleted index files being held by solr. Before the migration, we had 15-30% of disk space used, after the migration we have 60-90% of disk space used.
We are using Solr Cloud with 2 collections. The commands applied on the collections are: - for incremental indexation mode: add, deleteById with commitWithin of 30 minutes - for full indexation mode: add, deleteById, commit - for switch between incremental and full mode: deleteByQuery, createAlias, reload - there is also an autocommit every 15 minutes We have seen the email "Solr leaking references to deleted files" 2016-05-31 which describe the same problem but the mentioned bugs are fixed. We manually tried to force a commit, a reload and an optimize on the collections without effect. Is a problem of configuration (merge / delete policy) or a possible regression in the Solr code ?
