Change subject: core: DB upgrade from 3.0 to 3.1 fails(#880350) ...................................................................... core: DB upgrade from 3.0 to 3.1 fails(#880350) upgrade from 3.0.x to 3.1 failed in 2 points ; 1) 03_01_0950 Reason : script assumes that a storage is in only one DC and attempt to insert duplicate rows that violates primary key to the permission table Solution: check before inserting to permissions table that record with the same key does not exist 2) 03_01_1020 Reason :script adds a column_id column to the async_tasks table. Since this column type is UUID and is defined as NOT NULL, the addition will fail if at the point that this upgrade script is running the table is not empty Solution : Create the column with an empty UUID (00000.....000000) DEFAULT After this column was added , drop the default.
