Hi, I know for the option 'verify', we could specify it when we write and read a file. But does it work with the option 'time_base' and 'runtime'? For example, does the configuration below make sense? [global] direct=1 ioengine=libaio time_based numjobs=1 verify=crc32 runtime=50000 The verification process might not even start if the runtime ends, right? If this is the case, what should I do to configure it in such a way that it could do the read and write and also data verification in some targeted period of time? Thank you so much in advance. Best wishes, Taylor
