Hi!
You should make an unformatted partition whose size is
divisible by 1 MB. If fseek does not understand the partition size,
we can disable the size check from InnoDB code.
Please report if you succeed. If not, I change InnoDB-3.23.40
so that you can disable the file size check.
I haver not tested raw disks on Unix. Other problems may also
arise. For example, what does Linux do if fsync is called on
a raw disk partition? I hope Linux ignores such OS calls.
Regards,
Heikki
