SQLException: "The table is full" during SonarQube 6.7 LTS upgrade - mysql

Question

We've been using SonarQube for a long time, upgraded over many versions and now executed the long awaited LTS upgrade from version 5.6.6 to 6.7. Unfortunately, the database migration failed due to an SQLException "The table 'project_measures' is full".
Are there any guidelines about what do in such a case?
Is it not okay to upgrade directly from version 5.6.6 to 6.7? Should I first upgrade to some other intermediate version? I thought LTS-to-LTS upgrades should work out fine...

SonarQube is installed on a RHEL7 host using MySQL (rh-mysql57-mysql-server). The database location is /var/opt/rh/rh-mysql57/lib/mysql/sonar and there is free disk space available (but maybe not enough?):
/dev/mapper/vg0-var_opt 20G 17G 3.1G 85% /var/opt

Answer 1

Upgrade 5.6.6 to 6.7 is supported. According to your stack trace you are using MySQL server.
Can you have a look at server log files and the free space available on MySQL (maybe there is no enough space on your MySQL server for the migration) ?
