It does not auto refresh. I assume you did though. There is an option to dump all the zk state to the clipboard - can you attach that dump here? > SolrCloud admin graph is showing leader as state recovery failed, but it's > working > -- > > Key: SOLR-3859 > URL: https://issues.apache.org/jira/browse/SOLR-3859 > Project: Solr > Issue Type: Bug > Components: SolrCloud >Affects Versions: 4.0-BETA > Environment: linux/centos >Reporter: Jim Musil > > I'm not sure this is truly a bug, but the behavior really confuses me. > I have four servers running one of my cores.

This happened on ec2, so it's not that uncommon to take multiple servers down at once. My theory is that when a leader goes down, a new leader is chosen, but if the new leader has also gone down, then the remaining nodes cannot recover properly. Then, if the node that failed to recover is elected leader, it stays in that same "recovery failed" state. > SolrCloud admin graph is showing leader as state recovery failed, but it's > working > -- > > Key: SOLR-3859 > URL: https://issues.apache.org/jira/browse/SOLR-3859 > Project: Solr > Issue Type: Bug > Components: SolrCloud >Affects Versions: 4.0-BETA > Environment: linux/centos >Reporter: Jim Musil >Assignee: Mark Miller > Attachments: zkAdminScreen.PNG, zkDump.txt > > > I'm not sure this is truly a bug, but the behavior really confuses me. > I have four servers running one of my cores.
