I changed the innodb_log_file size from 1GB to 4GB and restarted Mysql, but noticed that ls -lah ib_logfile* still showed 1GB so I restarted Mysql again, this time the ib_logfile* showed 4GB but now the error log is filled with:
InnoDB: is in the future! Current system log sequence number 139654003953.
InnoDB: Your database may be corrupt or you may have copied the InnoDB
InnoDB: tablespace but not the InnoDB log files
Mysql is running and appears to be OK. If I shut down Mysql and move the ib_logfiles will Mysql recreate the logs and fix the error log entries?
