Depending on your setup, this may introduce a big performance impact on your
cluster. As an alternative, you can create a new pool and move disks separately.

+WARNING: When using the autoscaler, all pools must either exclusively be assigned
+device-specific or device-unspecific CRUSH rules. Mixing them across pools will
+prevent the autoscaler from functioning.
