Got error N from storage engine
Production Risk
High — root cause unknown until the embedded error code is investigated.
ER_GET_ERRNO (1030, SQLSTATE HY000) is a generic wrapper raised when the storage engine returns an error code that MySQL maps to a human-readable message. The embedded number N is the storage-engine-specific error code.
- 1InnoDB tablespace is corrupt or missing
- 2Storage engine returns an unexpected internal error
- 3Disk I/O error during a read or write
-- Typically surfaces as: ERROR 1030 (HY000): Got error 28 from storage engine
expected output
ERROR 1030 (HY000): Got error 28 from storage engine
Fix
Map the error number to its storage engine meaning
WHEN Always — the embedded number is the key diagnostic.
-- Common codes for InnoDB: -- 28 = no space left on device -- 139 = row too large -- 1005 / errno 150 = FK issue -- Run: SHOW ENGINE INNODB STATUS\G for detail
Why this works
Each storage engine has its own error numbering; look up the code in the engine documentation.
✕ Treat all 1030 errors the same way
The embedded error number varies widely; the fix for "disk full" (28) is completely different from "row too large" (139).
