MySQL server crash on TRUNCATE table with foreign key constraints - mysql

Question

I was running a web UI named pterodactyl panel : https://pterodactyl.io/ and after days of working fine, it crashed with the error message "Out of storage".
Obviously I did check and found that the disk was full, upon further investigation, a table named activity_logs in the panel database was using up almost 120 GB of space. I decided to clear the logs as I did not need them. I went ahead with a vacate command TRUNCATE. This was followed by an error:
Database changed
MariaDB [panel]> TRUNCATE TABLE activity_logs;
ERROR 1701 (42000): Cannot truncate a table referenced in a foreign key constraint (`panel`.`activity_log_subjects`, CONSTRAINT `activity_log_subjects_activity_log_id_foreign` FOREIGN KEY (`activity_log_id`) REFERENCES `panel`.`activity_logs` (`id`))
I went ahead and disabled key constrains and ran TRUNCATE in the hopes that I would enable forgeign key checks once the table is empty.
Expected:
SET FOREIGN_KEY_CHECKS = 0;
TRUNCATE TABLE activity_logs;
SET FOREIGN_KEY_CHECKS = 1;
exit;
What I got instead was:
MariaDB [panel]> SET FOREIGN_KEY_CHECKS = 0;
Query OK, 0 rows affected (0.000 sec)
MariaDB [panel]> TRUNCATE TABLE activity_logs;
ERROR 2013 (HY000): Lost connection to MySQL server during query
MariaDB [panel]> TRUNCATE TABLE activity_logs;
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)
ERROR: Can't connect to the server
unknown [panel]> exit
Bye
Not sure what to do in order to fix the issue.
Here is the log that i ran after:
root#Panel:/var/lib/mysql/panel# systemctl status mysql
