Hi Ben, Please see this thread https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/PWHG6QJ6N2TJ... for possible workaround. 发自我的 iPad 在 2023年10月10日，22:26，Ben <ruidong.gao@gmail.com> 写道： Dear cephers, with one osd down(200GB/9.1TB data), rebalance takes 3 hours still in progress. Client bandwidth can go as high as 200MB/s. With little client request throughput, recovery goes at couple MB/s. I wonder if there is configuration to polish for improvement. It runs with quincy 17.2.5, deployed by cephadm. The slowness can do harm in peak hours of usage.
