What should I do when I see a collection "recovering" in SolrCloud?
Should I stop indexing new documents, or stop indexing and wait for collections to recover?
Recently our disk got 100% full and Solr started to throw various errors. So I deleted some unnecessary documents and committed with expungeDeletes=true. It freed some space but many collections went into recovery mode.
Is there a guideline on how to react to such situations?
