Hi, I'm facing the same problem with Solrcloud 7x - 8x. I have TLOG type of replicas and when I delete Leader, log is always full of this: 2019-12-28 14:46:56.239 ERROR (indexFetcher-45942-thread-1) [ ] o.a.s.h.IndexFetcher No files to download for index generation: 7166 2019-12-28 14:48:03.157 ERROR (indexFetcher-45881-thread-1) [ ] o.a.s.h.IndexFetcher No files to download for index generation: 10588 Unfortunately, by this error it's hard to say even what exact replica, shard and collection is in trouble. Sometimes, indexing helps - my guess that after commit slave replicas somehow understands what index generation should be retrieved from new leader. Sometimes I have to restart node.
