The reason for that is that only few databases can run DDL statements (statements that change the database's structure) in a transaction, so that they can roll back a partly failed migration. The databases where this is supported are: - PostgreSQL - IBM DB2 The integrated H2 database as well as MySQL, MariaDB, Oracle RDBMS, Microsoft SQL Server and most others require either manual intervention or a backup to fully roll back to a previous database structure after a partially applied migration. We will consider having LINSTOR backup the database automatically before trying a migration, so that going back to an older version would be easier. br, Robert _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
