Hi, [~shm]!
>From such messages, I see that the archive is being cleaned, for example, is
>there *000000000000009.wal* segment after the test?

> Incorrect calculation of WAL segments that should be deleted from WAL archive
> -----------------------------------------------------------------------------
>
> Key: IGNITE-13912
> URL: https://issues.apache.org/jira/browse/IGNITE-13912
> Project: Ignite
> Issue Type: Bug
> Components: persistence
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Critical
> Fix For: 2.10
>
> Attachments: server1-full-wal-checkpoint.log, wal-checkpoint-logs,
> wal_dir_contents, wal_grows_from_peak.PNG, wal_issue_reproduced.PNG,
> wal_usage.PNG, wal_usage_dec12.PNG, wal_usage_dec22nd_binary.PNG
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Now there is an incorrect calculation of WAL segments that should be deleted
> from WAL archive. Since we delete only those segments whose total size should
> not exceed *DataStorageConfiguration#maxWalArchiveSize *
> IGNITE_THRESHOLD_WAL_ARCHIVE_SIZE_PERCENTAGE*, but should be up to
> DataStorageConfiguration#maxWalArchiveSize *
> IGNITE_THRESHOLD_WAL_ARCHIVE_SIZE_PERCENTAGE*. Therefore, an excess of
> *DataStorageConfiguration#maxWalArchiveSize* occurs.
