we have upgrade a SLES 12.1 to 12.5. After the update the installed mariadb won’t start.
The database wasn’t upgraded. So we started mariadb with “mysqld_safe”, did the upgarde of the tables,
but now we get the error message:
mysql-systemd-helper: chmod: changing permissions of '/usr/local/mysql/data': Read-only file system
The filesystem IS readable!
Also we can start the database using
The everything is working and the DB can be accessed. However we do not understand why
“rcmysqld” restart or “service mysql restart” is not working.
How can we debug this problem ?
Any idea is well come!
