Re: Failed to start mysql due to start_lsn and ens_lsn issue

8.0.30 seems to have radically changed redo log implementation (ib_logfile0 and ib_logfile1) with a much more complex (not to mention opaque) file arrangement. Now, redo log files use an #ib_redoN naming convention, where N is the redo log file number, and a blizzard of new configuration variables controls the new implementation (

Before 8.0.30, we could just move ib_logfile* to another folder and MySQL would rebuild them automatically. I don't know if there's an equivalent possibility in 8.0.30. If there are any such files present, you could move them to another location and see if they get rebuilt.

And, do you have a backup from before the crash?
