Subject [jira] Commented: (ZOOKEEPER-167) Content needed: "Troubleshooting"
Date Mon, 20 Oct 2008 21:25:44 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641159#action_12641159

Patrick Hunt commented on ZOOKEEPER-167:
----------------------------------------

In the ops guide we should have something detailing how to recover from datadir corruption.
In 3.0 we added CRCs to the snapshot and transaction log files. If we find a fault the user
may need to manually recover. Should have documentation re:

1) corrupted log file - server will attempt to recover automatically by dropping back to previous
snap/logs.
2) corrupted snapshot - user will need to manually intervene, recover datadir from redundant
server.
etc...

should include steps on how to do this.

deployment of ZooKeeper has problems.
