Could you provide any links describing how to tune > the scrub and snap trim thread pool IO priority? I couldn't find these > settings in the docs. It's osd disk thread ioprio class = idle osd disk thread ioprio priority = 0 Note that this is a short-term solution; we eventaully want to send all IO through the same queue so that we can prioritize things more carefully. This setting will most likely go away in the future. > IIUC, 0.67.11 does not include the proposed changes to address #9487 or > #9503, right? Correct. That will come later once it's gone through more testing. Thanks! sage
