> Key: IGNITE-20419
> URL: https://issues.apache.org/jira/browse/IGNITE-20419
> Project: Ignite
> Issue Type: Bug
> Reporter: Ivan Bessonov
> Assignee: Ivan Bessonov
> Priority: Major
> Labels: ignite-3
>
> This code:
> {code:java}
> storage.runConsistently(locker -> {
> storage.lastApplied(maxLastAppliedIndex, maxLastAppliedTerm);
> return null;
> }); {code}
> Here we don't touch any pages. As a result, updated index value may not be
> persisted to the storage in the next checkpoint. This causes eventual
> exception on restart:
> {noformat}
> java.lang.IllegalArgumentException: Try to truncate logs before 336, but the
> firstLogIndex is 370
> at
> org.apache.ignite.raft.jraft.util.Requires.requireTrue(Requires.java:92)
> ~[main/:?]
> at
> org.apache.ignite.raft.jraft.storage.impl.LogManagerImpl.truncatePrefix(LogManagerImpl.java:997)
> ~[main/:?]
> at
> org.apache.ignite.raft.jraft.storage.impl.LogManagerImpl.setSnapshot(LogManagerImpl.java:654)
> ~[main/:?]
> ...{noformat}
> In checkpointer, we must check for changed meta as well.
> Everything here can be tested with unit tests.
