Problem in recovering...
Hi everyone,
We have a 3 nodes solrcloud cluster using solr operator. We are in version 8.11.1.
We have created a collection with 2 shards and 3 replicas on each shards.
We could index around 45 million documents, but since a few days, I could see that one node is “missing” 4.3 millions documents and is in the state of “recovering”.
And it doesn’t work, it is like stuck.
In the logs I get following error messages:

And at one point I got such stack-trace:

I’ve done on each indexes the command (without the exorcise argument):
java -cp lucene-core-8.11.1.jar -ea:org.apache.lucene... org.apache.lucene.index.CheckIndex
And I got on all 6 indexes the same message: “ No problems were detected with this index “
What should I do to recover from this situation?
Thank you in advance for all the help you can give me!
Kind regards,
Alessandro
