Description of problem: =========== When setting QoS bandwidth limits through the Ceph Dashboard (e.g., client read/write bandwidth), entering a value of 3 GB results in the CLI displaying a slightly higher value, such as 3.2 GB. This inconsistency can be confusing to users and may appear as a rounding or conversion discrepancy between the Dashboard and CLI. This issue is likely due to differences in how the units are calculated between the Dashboard UI and CLI backend. Version-Release number of selected component (if applicable): ------- # ceph --version ceph version 19.2.1-126.el9cp (cfd2907537ba633f7d638895efd70ef5d0f1c99b) squid (stable) How reproducible: ----- 2/2 Steps to Reproduce: ------ 1. Create NFS Ganesha cluster 2. Go to the Ceph Dashboard → NFS --> Select cluster --> Set QoS --> Set the read and write bandwidth to 3 GB for client 3. Use the CLI to retrieve the configured QoS values: # ceph nfs cluster qos get nfsganesha { "combined_rw_bw_control": false, "enable_bw_control": true, "enable_iops_control": true, "enable_qos": true, "max_client_iops": 5000, "max_client_read_bw": "3.2GB", "max_client_write_bw": "3.2GB", "qos_type": "PerClient" } Actual results: ============= The CLI returns the bandwidth value as 3.2 GB, which is slightly higher than the 3 GB set via the Dashboard. Expected results: ============= The CLI should return the value as 3.0 GB, matching what was set in the Dashboard. Both interfaces should use consistent unit representations and conversions to avoid confusion.
