Maybe I have been working too many long hours as I missed the obvious solution
of bringing down/up one of the Solr nodes backing one of the replicas, and then
the same for the second node. This did the trick.
Since I brought this topic up, I will narrow the question a bit: Would there
be a way to recover without restarting the Solr node? Basically to delete one
replica and then somehow declare the other replica the leader and break it out
of its recovery process?
Thanks,
Matt

Subject: How to recover a Shard
Hello,
I have a SolrCloud (4.10.1) where for one of the shards, both replicas are in a
"Recovery Failed" state per the Solr Admin Cloud page. The logs contains the
following type of entries for the two Solr nodes involved, including statements
that it will retry.
Is there a way to recover from this state?
Maybe bring down one replica, and then somehow declare that the remaining
replica is to be the leader? Understand this would not be ideal as the new
leader may be missing documents that were sent its way to be indexed while it
was down, but would be better than having to rebuild the whole cloud.
Any tips or suggestions would be appreciated.
Thanks,
Matt
