--------------------------------------------
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}
[14:51:00,852][SEVERE][main][IgniteKernal] Got exception while starting (will
rollback startup routine).
