> resetLostPartitions() leaves an additional copy of a partition in the cluster
> -----------------------------------------------------------------------------

> Key: IGNITE-10058
> URL: https://issues.apache.org/jira/browse/IGNITE-10058
> Project: Ignite
> Issue Type: Bug
> Reporter: Stanislav Lukyanov
> Priority: Major
>
> If there are several copies of a LOST partition, resetLostPartitions() will
> leave all of them in the cluster as OWNING.
> Scenario:
> 1) Start 4 nodes, a cache with backups=0 and READ_WRITE_SAFE, fill the cache
> 2) Stop one node - some partitions are recreated on the remaining nodes as
> LOST
> 3) Start one node - the LOST partitions are being rebalanced to the new node
> from the existing ones
> 4) Wait for rebalance to complete
> 5) Call resetLostPartitions()
> After that the partitions that were LOST become OWNING on all nodes that had
> them. Eviction of these partitions doesn't start.
> Need to correctly evict additional copies of LOST partitions either after
> rebalance on step 4 or after resetLostPartitions() call on step 5.
> Current resetLostPartitions() implementation does call checkEvictions(), but
> the ready affinity assignment contains several nodes per partition for some
> reason.
