The size values for the following metrics are actually in mebibytes (MiB)/gibibytes (GiB), not megabytes (MB)/gigabytes (GB): * memory [1] [2] * memory.* [1] * disk.root.size [2] * disk.ephemeral.size [2] * volume.size [3] * volume.snapshot.size/snapshot.size [4] * volume.backup.size/backup.size [5] * volume.provider.capacity.*/volume.provider.pool.capacity.* [6] * manila.share.size [7] Change the units in samples and Gnocchi metrics from MB/GB to MiB/GiB.
