Hi Alex, I saw your thread, but I think mine is a little bit different. I have only one message so far, and I want to better understand the issue. I would like to see whether there are any tunable parameters that could be adjusted to have an influence on this behavior. Kind regards, Laszlo On 12.04.2017 22:19, Alex Gorbachev wrote:

We have ceph 0.94.10. I am researching the same issue, but on 11 OSD nodes. You should be able to find my thread in this list. Looks like this could be a bug in kernels 4.4+, or a network issue.
