Cant start mariadb after switching Data Directory - mariadb

Im trying to switch the data directory of mariadb to my HDD drive. But if i change datadir variable in the 50-server.cnf, mariadb wont start.
I have already modified the new directory with chmod and chown.
After switching the directory i get this message:
pi#raspberrypi:/etc/mysql/mariadb.conf.d $ sudo systemctl restart mariadb
Job for mariadb.service failed because the control process exited with error >code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.
This is the Error:

radiusd.service: Control process exited, code=exited status=1

I am very new to linux and freeradius and want to learn about this for my work, however I encounter some challenges.
I have installed freeradius on Centos 8. I installed it and it worked just fine but after installing mariaDB, issues came out when trying to start the service.

I've been dealing with this since yesterday and I tried searching for other related problems but cannot find some answers so I try asking for help here. Any help would be appreciated.
Thank you

MariaDB server is down after reboot

I needed to know my mariadb version but there's a typo mysqld -version (I installed it via apt, it was working with cli login, but not mysqli). The command jammed and I forced reboot the VPS from the panel. When it went up, I could not start mariadb.

I saw this:

I read this.

I did this
rm /var/lib/mysql/ib_logfile*
And worked for me.

Why does /etc/mysql/debian-start give me this error when starting MariaDB on Linux Mint?

I am setting up multiple instances of MariaDB on Linux Mint 20.2. I have managed to get the first one set up, and it seems basically OK (I can connect to a database, and by querying the MariaDB variables, can verify that the socket, port etc. match what I put in the configuration file). However, I am getting a confusing error, not from the server process itself, but from the associated systemd script. This is what happens when I start the service and then check the status :

Could it be that it is complaining about not being able to connect through a socket because I have specified "protocol = tcp" in the "client.cnf" section (I did this so I could just enter "mysql -P 3307 ..., mysql -P 3308" etc, instead of having to type in the socket path)? But in any case, should it be running that script anyway? The "debian-start" script is called by mariadb#.service, but if you look at the "debian-start" script itself, it actually contains this line:
NOTE: This file is read only by the traditional SysV init script, not systemd.
So should I just remove from mariadb#.service that call to debian-start?

MariaDB Won't Start After Installing

I'm running an Ubuntu 20.4 server and I've recently removed mysql-server and mysql-client and am trying to get MariaDB up and running. I've installed both mariadb-server and mariadb-client. I stop and then try to restart maria db. I get the general error message:
Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.
I then run systenctl status mariadb.service and get the below:

I've tried purging everything related to mysql and mariadb and reinstalled mariadb multiple times, but run into the same issue.

A galera node went down and started reporting error innodb as unknown or unsupported engine

One of my node was down and it was also the donor for the node A, so from node A config I removed the down node as donor. This is so that node A should not have to wait for the node to come up.
As the node that originally went down was on slow storage and slow network connection I decided to remove it. As I removed it and restarted the cluster even the node A didn't come up, on restart it started reporting error:

Why it started reporting Unknown/unsupported storage engine innodb now when it was working all this time?
Incidentally, I used another third node to bootstrap (start Galera_new_cluster).
