Hi Mosharaf, Can you please create a tracker issue and attach a copy of your osdmap? Also, please include any other output that characterizes the slowdown in client I/O operations you're noticing in your cluster. I can take a look once I have that information, Thanks, Laura On Wed, Sep 13, 2023 at 5:23 AM Mosharaf Hossain < mosharaf.hossain@bol-online.com> wrote:
Hello Folks We've recently performed an upgrade on our Cephadm cluster, transitioning from Ceph Quiency to Reef. However, following the manual implementation of a read balancer in the Reef cluster, we've experienced a significant slowdown in client I/O operations within the Ceph cluster, affecting both client bandwidth and overall cluster performance.
This slowdown has resulted in unresponsiveness across all virtual machines within the cluster, despite the fact that the cluster exclusively utilizes SSD storage."
Kindly guide us to move forward.
