Hi,
So try enabling RBD writeback caching — see http://marc.info
/?l=ceph-develm=133758599712768w=2
will test tomorrow. Thanks.
Can we path this to the qemu-drive option?

Hi,
For Stefan:
Increasing socket memory gave me about some percents on fio tests
inside VM(I have measured
'max-iops-until-ceph-throws-message-about-delayed-write' parameter).
What is more important, osd process, if possible, should be pinned to
dedicated core or two, and all other processes

I have a question about ceph.
When I mount ceph, I do the command as follow :
