The MariaDB database of a running SMT server is corrupted and must be re-created.


In order to re-create a corrupted database, open a root session on the SMT server and follow these steps:

1- Stop SMT and MariaDB services with:

# systemctl stop apache2.service

# systemctl stop mysql.service

# systemctl stop smt.service

2- Double-check that services are stopped:

# systemctl status apache2.service

# systemctl status mysql.service

# systemctl status smt.service

3- Once all services are stopped, create a backup copy of the SMT configuration file:

# cp -p /etc/smt.conf /etc/smt.conf.bck

4- Then proceed with the uninstallation of MariaDB:

# zypper remove mariadb mariadb-client mariadb-errormessages libmysqlclient18 perl-DBD-mysql

5- Once the packages are removed, then clean-up manually all the database files:

NOTE: deleting files in /var/lib/mysql/ will destroy all MariaDB databases and data.

# rm -rf /var/lib/mysql/*

6- Reinstall MariaDB with:

# zypper install mariadb mariadb-client mariadb-errormessages libmysqlclient18 perl-DBD-mysql smt

7- Start the MariaDB service:

# systemctl start mysql.service

# systemctl status mysql.service

8- Set the root password for MariaDB with:

# /usr/bin/mysqladmin -u root password 'NEW-PASS-HERE'

9- Create SMT database, follow the instructions on screen, set a password for the "root" user, then create the user "smt" and assign it the same password used for the "root" user.:

# /usr/lib/SMT/bin/smt-db setup

10- Initialize the SMT database with:

# /usr/lib/SMT/bin/smt-db migrate
# /usr/bin/smt-schema-upgrade

11- Restore the SMT configuration file from the backup copy, and assign the proper permissions to the SMT related files:

# cp -p /etc/smt.conf.bck /etc/smt.conf

# /usr/lib/SMT/bin/ -y --user smt

12- Restart MariaDB and start SMT services:

# systemctl start smt.service

# systemctl start apache2.service

# systemctl restart mysql.service

13- Once the SMT is up and running, run the reset and the sync operations:

# smt-register --debug --verboselevel 127 --reseterror

# smt-sync --debug --verboselevel 127 --logfile /tmp/smt-sync-d3.txt
