--------------------------------------------

             Summary: Changing walSegments property leads to fallen node
                 Key: IGNITE-10672
                 URL: https://issues.apache.org/jira/browse/IGNITE-10672
             Project: Ignite
          Issue Type: Bug
            Reporter: Dmitry Sherstobitov


Start cluster with        

{code}
 <property name="dataStorageConfiguration">
            <bean class="org.apache.ignite.configuration.DataStorageConfiguration">
                <!-- Enabling Apache Ignite Persistent Store. -->
                <property name="defaultDataRegionConfiguration">
                    <bean class="org.apache.ignite.configuration.DataRegionConfiguration">
                        <property name="persistenceEnabled" value="true"/>
                    </bean>
                </property>
                <property name="walSegments" value="5"/>
            </bean>
        </property>
{code}

Load some data and then restart cluster with new config:
{code}
 <property name="dataStorageConfiguration">
            <bean class="org.apache.ignite.configuration.DataStorageConfiguration">
                <!-- Enabling Apache Ignite Persistent Store. -->
                <property name="defaultDataRegionConfiguration">
                    <bean class="org.apache.ignite.configuration.DataRegionConfiguration">
                        <property name="persistenceEnabled" value="true"/>
                    </bean>
                </property>
                <property name="walSegments" value="4"/>
            </bean>
        </property>
{code}

This will lead node to error on start
{code}
