The initial stall is gone, but the test got hung at the 'stonewall' sequence again: [global] bs=4k ioengine=libaio iodepth=256 size=4g direct=1 runtime=60 # directory=/mnt numjobs=32 group_reporting cpus_allowed_policy=split filename=/dev/md127 [seq-read] rw=read -> stonewall [rand-read] rw=randread stonewall Restarting all queues made the fio job continue. There were 4 queues with state 'restart', and one queue with state 'active'. So we're missing a queue run somewhere.
