Hi,

How do you check that partitions were created or not?

Hi  Andrei,
Could  it  be possible  that  multiple  processes  running  in  each individual  host  can  result  in  backup  partitions  not getting  generated? 

Thanks

Hi Andrei,
I  am  using In  memory  clusters and  my  cluster  is  having  3  nodes. Here  is  the  o/p  when  I  run  the  command  .  Are  you saying  we  need  to  add  the  other  nodes here? 

Thanks

Satyajit

Hi,

You probably only have one data node in the baseline topology:
https://ignite.apache.org/docs/latest/clustering/baseline-topology# <https://clicktime.symantec.com/39fUWTjERvYZLygCp3H7YbC6H2?u=https%3A%2F%2Fignite.apache.org%2Fdocs%2Flatest%2Fclustering%2Fbaseline-topology%23> 

Try to check how many nodes you have there and add new nodes?

    Hi  Team,

    I  have  a  cache  configuration  setup as  below with backups  =1
    . But  when I  check  the  cache statistics  using  visor  I 
    don’t see  any  backup partition  getting  generated.  Can 
    someone  explain under  what  situations  this  can happen.  We 
    are using thin  client.

    <bean class="org.apache.ignite.configuration.CacheConfiguration">

    <property name="name" value="default"/>

    <property name="atomicityMode" value="ATOMIC"/>

    <property name="cacheMode" value="PARTITIONED"/>

    <property name="backups" value="1"/>

    <property name="onheapCacheEnabled" value="true"/>

    </bean>

              </list>

            </property>

    Thanks
