Starting with MariaDB 10.8.1 the ib_logfile0 is required and should not be deleted (ref. MDEV-27199: Require ib_logfile0 to exist.

- what about logfile1?

[pfrenssen]

logfile1 is seemingly already obsolete in MariaDB since 10.5.0. In that version they switched to using 1 single log file. I found the ticket: MDEV-20907: Set innodb_log_files_in_group=1 by default.
