MariaDB Error 1208: Global Read Lock Prevents Drop
Description
This error occurs when an attempt is made to drop a database while another thread or operation holds an active global read lock. The global read lock prevents any data definition language (DDL) operations, such as dropping a database, to ensure data consistency and integrity across the server. It indicates that the system is in a state where no structural changes are permitted.
Error Message
DROP DATABASE not allowed while thread is holding global read lock
Known Causes
3 known causesManual Global Read Lock Active
An administrator or another application has explicitly executed `FLUSH TABLES WITH READ LOCK` in a different session, which places a global read lock on all tables, preventing DDL operations.
Backup Operation In Progress
A database backup utility (e.g., `mysqldump` or other tools) is currently running and has acquired a global read lock to ensure a consistent snapshot of the data, blocking structural changes.
Replication or Maintenance Tasks
The MariaDB server might be acting as a replication slave, or undergoing specific maintenance tasks that implicitly require a global read lock to maintain data integrity during the process.
