Hi ,Greg , thank you for your suggestions.

I run six times for the command: "$ sudo ceph osd tell 0/1 bench "
use "$ sudo ceph -w" to get the following results:

I run twice for the command: "rados -p data bench 60 write" ,
Get the results:
$ sudo rados -p data bench 60 write

but run "$ sudo rados -p data bench 0 seq"
fail to get the results, Maybe it's a bug,ceph version 0.23.
