Checkpoints and advancing the checkpoint LSN are not permitted until redo log recovery is complete and data dictionary dynamic metadata (srv_dict_metadata) is transferred to data dictionary table (dict_table_t) objects. Should the redo log run out of space during recovery or after recovery (but before data dictionary dynamic metadata is transferred to data dictionary table objects) as a result of this change, an innodb_force_recovery restart may be required, starting with at least the SRV_FORCE_NO_IBUF_MERGE setting or, in case that fails, the SRV_FORCE_NO_LOG_REDO setting. If an innodb_force_recovery restart fails in this scenario, recovery from backup may be necessary.
