Thanks Mark. Unfortunately I only took log file backup of the Solr instance which failed.
Even if we stopped and started all instances in a shard at same time, isn't there a possibility that the Solr Instance with less data (or no data) might declare itself leader and the one with the data will start copying the empty index folder from the leader? We tried using the latest branch_4x few weeks back and hit the SOLR-4144 <https://issues.apache.org/jira/browse/SOLR-4144> issue. Although it was fixed in a day, we decided to use the released version only (4.0) since we cannot have such extended periods of outage. We are looking forward to 4.1 and will start using it as soon as its released. --Shreejay -- View this message in context: http://lucene.472066.n3.nabble.com/Data-from-deleted-from-Solr-Solr-cloud-tp4028055p4029212.html Sent from the Solr - User mailing list archive at Nabble.com.
