Catalog Search indexer process unknown error: SQLSTATE[HY000]: General error: 1813

Question

    **Catalog** **Search indexer** process unknown error:
SQLSTATE[HY000]: General error: 1813 Tablespace for table '`mydb`.`catalogsearch_fulltext_scope1_tmp`' exists. Please DISCARD the tablespace before IMPORT., query was: CREATE TABLE IF NOT EXISTS `catalogsearch_fulltext_scope1_tmp` (
  `entity_id` int UNSIGNED NOT NULL COMMENT 'Entity ID' ,
  `attribute_id` int UNSIGNED NOT NULL COMMENT 'Attribute_id' ,
  `data_index` longtext NULL COMMENT 'Data index' ,
  PRIMARY KEY  (`entity_id`, `attribute_id`),
  FULLTEXT `FTI_FULLTEXT_DATA_INDEX` (`data_index`)
) COMMENT='catalogsearch_fulltext_scope1_tmp' ENGINE=innodb charset=utf8 COLLATE=utf8_general_ci

When I try to do reindex I have this error. If I look into db for this table catalogsearch_fulltext_scope1_tmp it does not exists. But instead i sea that exist a table named catalogsearch_fulltext_scope2. I've tried to delete the catalogsearch_fulltext_scope1_tmp but there is no table in db...

The Magento is vs 2.2.0, PHP 7.0.25,

Answer 1

a possible solution i found here Error: Tablespace for table xxx exists. Please DISCARD the tablespace before IMPORT

...so to solve this you must have permissions on server to delete manually the table space..., i didn't somebody else solve this, a server admin or so...
