P.S. Is there a way to tell which client has mapped certain rbd if no
rbd lock is used?
What you could do is this:
$ rbd lock add myimage `hostname`
That way you know which client locked the image.

It would be useful to

Hi Sage,
i am appreciated for your reply.
by my understanding on reading the client codes, i think ceph
allocates msg based on individual file. In another word, if one client
is updating on different files (each file is doing small
writes/updates, i.e. 4kb), ceph has to compose different msgs
Hi,
Could provide those heaps? Is it possible?

Well ideally you want to run the profiler during the scrubbing process

The only way I can see that this would happen is if maps were being
generated much more quickly than pgs could be updated...the solution
to that would be to throttle new map handling to the rate at which PGs
consume them at the OSD. Alternately, you could tweak the map
creation rate at the mons.

We're updating this weekend to 0.56.1.
If it still happens after the update, I'll try and reproduce it on our
test infra and do the profile there, because unfortunately running the
profiler seem to make it eat up CPU and RAM a lot ...
I also need to
Hi Sage,
i see the Pipe class is a very important structure on server side. It
has two threads for read/write messages on the connected socket.
For example, if one client send write request to an OSD, the reader
read the msg and get parse the msg such as msg type, data and so on.
so the msg type

Hi Isaac,
Could you send us your routing tables on the osds (route -n).
If the S3 API is not well suited to my scenario, then my effort should
be better directed to porting or writing a native ceph client for
Windows. I just need an API to read and write/append blocks to files.
Any comments are really appreciated.
Hopefully someone with more windows experience
Have you tried rest-bench on localhost at the rados gateway? I was
playing with the rados gateway in a VM the other day, and was getting
up to 400/s on 4k objects. Above that I was getting connection
failures, but I think it was just due to a default max connections
setting somewhere or something.
