Issue with libaio on one Ceph 1.15 cluster:

/ # fio --name=random-writers --ioengine=libaio --iodepth=4 --rw=randwrite --bs=32k --direct=0 --size=64m --numjobs=4

remove the use of libaio and the test works.

Got the same issues with v0.4.46, rolled back to v0.4.44 and it's fine.

My command was slightly different though:
