点燃控制工具命令"reset_lost_partitions“不工作

Question

在所有服务器节点重新启动并重新加入基线之后，仍然无法读取或写入缓存：

javax.cache.CacheException: class org.apache.ignite.internal.processors.cache.CacheInvalidStateException: Failed to execute the cache operation (all partition owners have left the grid, partition data has been lost) [cacheName=SQL_DEV_MONI_MONITOR, partition=840, key=UserKeyCacheObjectImpl [part=840, val=iii, hasValBytes=false]]
    at org.apache.ignite.internal.processors.cache.GridCacheUtils.convertToCacheException(GridCacheUtils.java:1278)

节点拥有的分区被重新划分：

cacheGroups_public_LocalNodeOwningPartitionsCount{iin="fintech-test-grid-mcpl323", inci="7ffed004-2058-4045-875e-bca5ac37e12a", instance="10.16.23.47:9090", job="prometheus"}

cacheGroups_public_LocalNodeOwningPartitionsCount{iin="fintech-test-grid-mwpl037", inci="fcea873e-3822-4f1b-ab86-acf71d2e740b", instance="10.16.50.124:9090", job="prometheus"}

启用了数据区域持久性，但reset_lost_partitions不起作用：

        <property name="dataStorageConfiguration">
            <bean class="org.apache.ignite.configuration.DataStorageConfiguration">
                <!--
                    Default memory region that grows endlessly. A cache is bound to this memory region
                    unless it sets another one in its CacheConfiguration.
                -->
                <property name="defaultDataRegionConfiguration">
                    <bean class="org.apache.ignite.configuration.DataRegionConfiguration">
                        <property name="name" value="Default_Region"/>
                        <property name="persistenceEnabled" value="true"/>
                        <!-- 1 GB memory region with disabled eviction -->
                        <property name="initialSize" value="#{100L * 1024 * 1024}"/>
                        <property name="maxSize" value="#{100L * 1024 * 1024 * 1024}"/>
                        <!-- Enabling SEGMENTED_LRU page replacement for this region.  -->
                        <property name="pageReplacementMode" value="SEGMENTED_LRU"/>
                        <property name="metricsEnabled" value="true"/>
                        <property name="warmUpConfiguration">
                            <bean class="org.apache.ignite.configuration.LoadAllWarmUpConfiguration"/>
                        </property>
                    </bean>
                </property>
            </bean>
        </property>

如果节点已永久离开网格，则需要更新基线拓扑。有许多方法可以做到这一点，但最简单的方法是控制脚本：

./control.sh --baseline 

然后

./control.sh --baseline add [node]
./control.sh --baseline remove [node]
