我在activemq队列（使用主从配置）中面临消息被击中的问题，当我将大约100条消息泵送到不同的队列时，消费者无法使用消息

我在两个独立的linux实例中以主从模式配置了ActiveMQ（v5.9.0）MessageBroker。对于这两个实例上的persistenceAdapter conf，我已将NAS存储装载到运行activemq服务器的两个实例上。因此，在装载点“/mnt/NAS”的两个activemq实例上都装载了相同的NAS存储。NAS存储的大小为20 GB

我的persistenceAdapter配置如下所示

<persistenceAdapter>
      <kahaDB directory="/mnt/nas" ignoreMissingJournalfiles="true" checkForCorruptJournalFiles="true" checksumJournalFiles="true"/>
</persistenceAdapter>

<systemUsage>
        <systemUsage>
            <memoryUsage>
                <memoryUsage percentOfJvmHeap = "70"/>
            </memoryUsage>
            <storeUsage>
                <storeUsage limit = "15 gb"/>
            </storeUsage>
            <tempUsage>
                <tempUsage limit = "7 gb"/>
            </tempUsage>
        </systemUsage>
 </systemUsage>

因此，我看到使用了41%的/mnt/nas

问题是，当我启动activemq服务器（在两个实例上）时，我在activemq.log中看到以下消息

我看到“在'/mnt/nas/db-1.log'中发现损坏的日志记录”。每次重新启动时都会出现这种情况，即使我删除此文件并重新启动。我已经设置了恢复标志，但每次重新启动都会出现此日志条目

另一个问题是，尽管我的NAS存储容量为20GB，但它显示“/mnt/NAS只有0 mb的可用空间”。这真的很奇怪。我不确定为什么activemq可以使用0 MB

我请求这里的人给我一些建议，说明为什么会发生这种情况，并建议我任何更好的配置，以避免消息在队列中被击中

谢谢

我刚刚调试了ApacheActiveMQ的源代码，发现当它尝试在挂载点/mnt/nas上获取可用空间（使用java.io.File.getUsableSpace（）方法）时，会得到0。不确定装载点返回0I的原因。我将把ActiveMq升级到更新的版本。5.9.0中也有一个bug：关于存储空间的bug在5.9.1中得到了修复。
