Hi, We are building huge test system with hundreds TB of data. We want to execute some performance tests without and with external log device. Filling in the data is a time consuming process, so my first idea was to create the filesystem without external log, execute the tests and then add external log and repeat the tests without recreating the filesystem. Now I know I have to do this.
