> Project: Ignite
> Issue Type: Bug
> Components: storage engines ai3
> Affects Versions: 3.1
> Environment: 3 node cluster either on single host or each on separate
> host.
> Reporter: Igor
> Assignee: Mirza Aliev

> *Steps to reproduce:*
> # Start cluster of 3 nodes on single host or each node on separate host on
> version 3.0.0.
> # Create tables and insert data:
> {code:java}
> create zone "DEFAULT_ZONE" with storage_profiles='default_aipersist'
> create TABLE test_table(id INTEGER not null, field_1 TINYINT not null,
> field_2 SMALLINT not null, field_3 INTEGER not null, field_4 FLOAT not null,
> field_5 VARCHAR(50) not null, primary key (id)) ZONE "DEFAULT_ZONE"
> insert into test_table(id, field_1, field_2, field_3, field_4, field_5)
> values (3356::INTEGER, 45::TINYINT, 22062::SMALLINT, -861252049::INTEGER,
> 0.0::FLOAT, '1field_5_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1'::VARCHAR)
> {code}
> 3. Validate data in tables
> {code:java}
> select id, field_1, field_2, field_3, field_4, field_5 from test_table {code}
> 4. Await all partitions of all tables in zones [DEFAULT_ZONE] local state is
> "HEALTHY" and global state is "AVAILABLE"
> 5. Install new distribution into cluster with full restart
> 6. Assert physical and logical topologies are correct
> 7. Await all partitions of all tables in zones [DEFAULT_ZONE] local state is
> "HEALTHY" and global state is "AVAILABLE".
> *Expected:*
> Partitions changed state to "HEALTHY"
> *Actual:*
> During 120 seconds partitions were in states `[INITIALIZING, HEALTHY]`.
> In logs on one node there are repeating messages:
> {code:java}
> 2025-09-10 04:02:04:678 +0000
> [INFO][%PdsCompatibility3NodesTest_cluster_0%JRaft-ElectionTimer-1][NodeImpl]
> Unsuccessful election round number 35, group '17_part_4' {code}
> Server logs are in attachment.
> The issue is flaky, but reproducible rate about 90%.
