When running fio-2.3 with the rbd engine, the tests themselves run fine, but instead of the results being printed, I get: fio: mutex.c:163: fio_mutex_down: Assertion `mutex->magic == 0x4d555445U' failed. The command I am using is fio --ioengine=rbd --clientname=admin --pool=test --rbdname=test1 --rw=randwrite --runtime=10 --ramp_time=None --numjobs=1 --direct=1 --bs=1048576B --iodepth=64 --name=test1 If I instead use another engine, everything is fine, e.g.: fio --ioengine=libaio --filename=/dev/sdb1 --rw=randwrite --runtime=10 --ramp_time=None --numjobs=1 --direct=1 --bs=1048576B --iodepth=64 --name=test1 Going back to fio-2.2.13 makes the error go away and running a git bisect leads to the commit mentioned in the subject as the culprit, the error turns into a Segmentation Fault at that point, though. -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
