Vernon,
You can use the rbd command bench-write documented here:
http://ceph.com/docs/next/man/8/rbd/#commands
The command might looks something like:
rbd --pool test-pool bench-write --io-size 4096 --io-threads 16
--io-total 1GB test-image
Some other interesting flags are --rbd-cache, --no-rbd-cache, and
--io-pattern {seq|rand}
Cheers,
Mike

Hi cephers,
I use "qemu-img create -f rbd rbd:test-pool/test-image" to create a
image. I want to know how can I check this image's IO. Or how to check
the IO for each block?
Thanks.
