----------------------------------------
Labels: ise (was: )
> Blinking node in cluster may cause data corruption
> --------------------------------------------------
>
> Key: IGNITE-8874
> URL: https://issues.apache.org/jira/browse/IGNITE-8874
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.5
> Reporter: Dmitry Sherstobitov
> Priority: Critical
> Labels: ise
>
> All caches with 2 backups
> 4 nodes in cluster
> # Start cluster, load data
> # Start transactional loading (8 threads, 100 ops/second put/get in each op)
> # Repeat 10 times: kill one node, clean LFS, start node again, wait for
> rebalance
> # Check idle_verify, check data corruption
> Here is idle_verify report:
> node2 - node that was blinking while test. Update counter are equal between
> partitions but data is different.
