<!--StartFragment-->Users who may upgrade their MySQL server after upgrading to Apache CloudStack 4.15 or later, may need to run the following SQL query to fix an issue with "cloud.nics" table's column type which may lead to exception seen in the management server logs<!--EndFragment--> This message is not complete/correct, because: as I stated, I had this message reported by 2 users even when upgrading from older ACS versions to ACS 4.14 and MySQL 5.7.xx (parallel updates we do with users, so also MySQL is of a newer, 5.7.xx version) - we historically had this column type set in a certain way - and as of MySQL 5.7.xx and MySQL 8 - all ACS versions are "broken" in that regards - i.e. no VM's can be started - and 1) in pre-4.15 used with MySQL 5..7.xx you still need to manually execute this statement to fix your 4.13, or 4.14 env, etc. 2) in 4.15, this statement can fail (weird enough) during the upgrade, and again needs to be executed manually. What I'm saying for both < 4.15 and >4.15 there are issues seen with MySQL 5.7.xx/8.x Hope that makes sense, or we can discuss offline. -- This is an automated message from the Apache Git Service.
