# The general reason why innodb redo log file is limited by 512G is that
# log_block_convert_lsn_to_no() returns value limited by 1G. But there is no
# need to have unique log block numbers in log group. This test forces innodb
# to generate redo log files with non-unique log block numbers and tests
# recovery process with such numbers.
