[jira] [Commented] (SOLR-4519) corrupt tlog causes fullCopy
download index files every time reboot a node
[ https://issues.apache.org/jira/browse/SOLR-4519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15538871#comment-15538871 ]

> 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:
