liutang123 opened a new issue #6320:
URL: https://github.com/apache/incubator-doris/issues/6320
1. `StorageEngine::_delete_tablets_on_unused_root_path` will try to obtain
tablet shard write lock in `TabletManager`
```
StorageEngine::_delete_tablets_on_unused_root_path
TabletManager::drop_tablets_on_error_root_path
obtain each tablet shard's write lock
```
2. `TabletManager::build_all_report_tablets_info` and other methods will
obtain tablet shard read lock frequently.
So, `StorageEngine::_delete_tablets_on_unused_root_path` will hold
`_store_lock` for a long time.
This will make it difficult for other threads to get write `_store_lock`,
such as `StorageEngine::get_stores_for_create_tablet`
`drop_tablets_on_error_root_path` is a small probability event,
`TabletManager::drop_tablets_on_error_root_path` should return when its param
`tablet_info_vec` is empty
