MySQL 9.5 Reference Manual Including MySQL NDB Cluster 9.5
      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.
