**How to reproduce**
Clickhouse server 20.13.1.5273
```
CREATE TABLE default.test
(
`key` UInt32,
`ts` DateTime CODEC(DoubleDelta, LZ4),
`db_time` DateTime DEFAULT now() COMMENT 'spout-ignore' CODEC(DoubleDelta, LZ4)
)
ENGINE = MergeTree
PARTITION BY toStartOfTenMinutes(db_time)
ORDER BY (key, ts)
TTL db_time + toIntervalHour(3)
SETTINGS index_granularity = 8192, merge_with_ttl_timeout = 3600, min_rows_for_compact_part = 1000000, min_bytes_for_compact_part = 200000000, in_memory_parts_enable_wal = 0;


INSERT INTO test(key, ts) SELECT number % 1000, now() + intDiv(number,1000) FROM numbers(500);

SELECT * FROM test;
500 rows in set. Elapsed: 0.003 sec.

DETACH TABLE test;

ATTACH TABLE test;

SELECT * FROM test;

0 rows in set. Elapsed: 0.002 sec.
```

**Expected behavior**
Clickhouse would flush parts on disk.
const String & name, const VolumePtr & volume, const String & relative_path, const IMergeTreeDataPart * parent_part) const
{
    return createPart(name, MergeTreePartInfo::fromPartName(name, format_version), volume, relative_path, parent_part);
}
MergeTreeData::MutableDataPartPtr MergeTreeData::createPart(
    const String & name, const MergeTreePartInfo & part_info,
    const VolumePtr & volume, const String & relative_path, const IMergeTreeDataPart * parent_part) const
{
    MergeTreeDataPartType type;
    auto full_path = fs::path(relative_data_path) / (parent_part ? parent_part->relative_path : "") / relative_path / "";
    auto mrk_ext = MergeTreeIndexGranularityInfo::getMarksExtensionFromFilesystem(volume->getDisk(), full_path);
    if (mrk_ext)
        type = getPartTypeFromMarkExtension(*mrk_ext);
    else
    {
        
        type = choosePartTypeOnDisk(0, 0);
    }
    return createPart(name, type, part_info, volume, relative_path, parent_part);
