Mark Miller commented on SOLR-9836:
-----------------------------------
bq. Possibly best to have two options
The third option is not very difficult. Lucene already loads the last segments
file it can. So if we get a corrupt index, we can just sanity check that the
segments file can be loaded. If it can't, we can't fix things anyway, so
recover. If the segments file looks fine, don't recover because the index could
be corrected.
> Add more graceful recovery steps when failing to create SolrCore

> I have seen several cases where there is a zero-length segments_n file. We
> haven't identified the root cause of these issues (possibly a poorly timed
> crash during replication?) but if there is another node available then Solr
> should be able to recover from this situation. Currently, we log and give up
> on loading that core, leaving the user to manually intervene.
