v0.47.1
Can you (from the KVM host) run "rados -p data bench seq 60 -t 1" "rados -p data bench seq 60 -t 16" and paste the final output from both?
I think your meant: rados -p data bench 60 seq -t 1 ? but even that results in: ~# rados -p data bench 60 seq -t 1 Must write data before running a read benchmark! error during benchmark: -2 error 2: (2) No such file or directory Stefan -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
