Tablespace already exists
Production Risk
Medium — the CREATE is rejected; existing tablespace is unaffected.
What this means
An InnoDB tablespace with the specified name already exists, typically when trying to create a general tablespace that was already created or when an orphaned .ibd file conflicts with a CREATE TABLE.
Why it happens
- 1CREATE TABLESPACE was called for a tablespace that already exists.
- 2An orphaned .ibd file from a previous table exists in the data directory.
How to reproduce
trigger — this will error
trigger — this will error
CREATE TABLESPACE ts1 ADD DATAFILE 'ts1.ibd' ENGINE=InnoDB; -- When ts1 already exists
expected output
ERROR 1677 (HY000): InnoDB: Tablespace 'ts1' already exists.
Fix 1
Drop the existing tablespace first if it is unused
Drop the existing tablespace first if it is unused
DROP TABLESPACE ts1; CREATE TABLESPACE ts1 ADD DATAFILE 'ts1.ibd' ENGINE=InnoDB;
Why this works
Dropping the conflicting tablespace allows the new one to be created.
Fix 2
Remove orphaned .ibd files
Remove orphaned .ibd files
-- Stop MySQL, remove the orphaned .ibd file, restart MySQL
Why this works
Orphaned files left from incomplete DROP TABLE can prevent new table creation.
