Jira Server でクラスタ ロックのヘルス チェックに失敗
In JIRA Data Centre some operations require the a lock to be placed across all nodes for operations that should only be operated on one node at a time, for example taking a backup of the index. This Health Check will check the age of the cluster locks and report a warning in the event that a cluster lock is found that is older than five minutes.
|The health check passed successfully.||No lock was detected that is older than five minutes.|
|Node '<||A lock has been held for longer than five minutes.|
|A Node has not released a lock.|
Check that the node reported in the health check is responsive and running. Review the logs of the node to see if there are any errors or exceptions.
In the event that the node is not running, or unresponsive, a restart of the affected node is expected to clear the lock. Prior to doing so it is recommended to collect thread dumps as per Generating a Thread Dump.
