Description
If you clone a server using `innodb-undo-tablespaces=4` to one that isn't, MariaDB server disables these with a warning:
2021-11-24 19:48:57 0 [Note] InnoDB: Opened 4 undo tablespaces
|
2021-11-24 19:48:57 0 [Warning] InnoDB: innodb_undo_tablespaces=0 disables dedicated undo log tablespaces
|
2021-11-24 19:48:57 0 [Note] InnoDB: 128 rollback segments in 4 undo tablespaces are active.
|
Subsequently trying to backup this instance with mariabackup fails:
