Hi,

The configuration file location between 10.4 and 10.5 differs and I didn't edit the default repo configuration file while using 10.4.11 so I don't believe that I had force-recovery enabled still while in 10.4.11.

Does it matter that the source operating system is 64 bit Windows for these files that I gathered using mariabackup?

Does windows use a different replay log format or something?

Here is the entire log entry while 10.4.11 was running:

Alright so I was able to get a little further (thank you so much):

Server version: 10.4.11-MariaDB MariaDB Server
...
MariaDB [(none)]> set global innodb_fast_shutdown = 0;
Query OK, 0 rows affected (0.000 sec)
MariaDB [(none)]> quit
Bye
[yum.repos.d]# systemctl stop mariadb

I then uninstalled 10.4.11, put the repos back to the default and installed 10.5.29-3 from RHEL9 distribution.

When I started mariadb it says this:

Anything else needed to check in 10.4.11 land prior to upgrading?

So you got it working with 10.4, without force-recovery, did a full
clean shutdown, and 10.5 still choked on the redo log??
The only thing I can think of is that you started 10.4 with
force-recovery still on so it came up read-only and did nothing on
shutdown to purge the redo log.
Anything interesting in the log during 10.4 startup?
