Hi, Occasionally stepping into couple of failures with FIO with arguments captured below So wanted to get opinion on if I am missing something in parameters Failure 1: The arguments passed are: sudo fio --thread --direct=1 --minimal --ioengine=libaio --numjobs=1 --filename=/dev/nvme0n1 -o /tmp/nvme0n1_temp.log --name=bs16384_rwwrite_qd256 --buffer_pattern=0 --iodepth=256 --size=409600 --percentage_random=0 --bs=256k --offset=625181037 --rw=write Error in FIO run: fio: io_u error on file /dev/nvme0n1: Invalid argument: write offset=625181037, buflen=262144 Error in FIO run: fio: io_u error on file /dev/nvme0n1: Invalid argument: write offset=625443181, buflen=262144 Failure 2: Write followed by verify: sudo fio --thread --direct=1 --minimal --ioengine=libaio --numjobs=1 --filename=/dev/nvme0n1 -o /tmp/nvme0n1_temp.log --name=bs16384_rwwrite_qd256 --buffer_pattern=1 --iodepth=256 --size=40960 --percentage_random=0 --bs=16384 --rw=write sudo fio --thread --direct=1 --minimal --ioengine=libaio --numjobs=1 --filename=/dev/nvme0n1 -o /tmp/nvme0n1_temp.log --name=bs16384_rwverify_qd256 --buffer_pattern=1 --iodepth=256 --size=40960 --percentage_random=0 --bs=16384 --rw=read --verify=pattern --verify_pattern=1 Error in starting FIO: fio: got pattern '00', wanted '01'.
