Fatal error usermod: user mysql is currently used by process

[Pepan]

I used this ansible role few years ago.
But today I updated this galaxy component and run for another project on same server.
I ended with :

TASK [bertvv.mariadb : Create daemon user with specified uid] *************************************************************************************************************************************************************************************************************************************************************************************************
fatal: [81.2.216.251]: FAILED! => {"changed": false, "msg": "usermod: user mysql is currently used by process 5741\n", "name": "mysql", "rc": 8}

It is obvious that there will be running proces and also existing user ...

What should I do?

I solved it by stopping mariadb server before running playbook. But it should do this role automatically I guess.
