**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.
std::lock_guard loading_lock(mutex);
            broken_parts_to_detach.push_back(part);
            ++suspicious_broken_parts;
            suspicious_broken_parts_bytes += size_of_part;
            return;
        }
        try
        {
            part->loadColumnsChecksumsIndexes(require_part_metadata, true);
        }
        catch (const Exception & e)
        {
            
            
            
            if (isNotEnoughMemoryErrorCode(e.code()))
                throw;
            broken = true;
            tryLogCurrentException(__PRETTY_FUNCTION__);
        }
        catch (...)
        {
            broken = true;
            tryLogCurrentException(__PRETTY_FUNCTION__);
        }
        
        if (broken)
        {
            
            size_t size_of_part = IMergeTreeDataPart::calculateTotalSizeOnDisk(part->volume->getDisk(), part->getFullRelativePath());
