Reporter: Igor Attachments: server_logs.zip
*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} # Validate data in tables {code:java} select id, field_1, field_2, field_3, field_4, field_5 from test_table {code} # Await all partitions of all tables in zones [DEFAULT_ZONE] local state is "HEALTHY" and global state is "AVAILABLE" # Install new distribution into cluster with full restart # Assert physical and logical topologies are correct # 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.
