Alexandre Rafalovitch commented on SOLR-4519:
---------------------------------------------
There does not seem to be a specific bug here anymore. Can it be closed?
> corrupt tlog causes fullCopy download index files every time reboot a node

> Key: SOLR-4519
> URL: https://issues.apache.org/jira/browse/SOLR-4519
> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.0
> Environment: The solrcloud is implemented on three servers. There are
> three solr instance on each server. The collection has three shards. Every
> shard has three replica. Replicas in same shard run in solr instance on
> different server.
> Reporter: Simon Scofield
>
> There are two questions:
> 1. The tlog of one replica of shard1 is damaged by some reason. We are still
> looking for the reason. Please give some clue if you are familia with this
> problem.
> 2. The error replica successed to recovery by fullcopy download index files
> from leader. Then I killed the instance and started it again, the recovery
> process still is fullcopy download. In my opinion, after the first time
> fullcopy recovery, the tlog should be fixed. Here is some log:
