Doc Type: Bug Fix
Doc Text:
.The correct CRUSH location of the OSDs parent (host) is determined Previously, when the `osd_memory_target_autotune` option was enabled, the memory target was applied at the host level. This was done by using a host mask when auto-tuning the memory. But the code that applied to the memory target would not determine the correct CRUSH location of the parent host for the change to be propagated to the OSD(s) of the host. As a result, none of the OSDs hosted by the machine got notified by the config observer and the `osd_memory_target` remained unchanged for those set of OSDs. With this fix, the correct CRUSH location of the OSDs parent (host) is determined based on the host mask. This allows the change to propagate to the OSDs on the host. All the OSDs hosted by the machine are notified whenever the auto-tuner applies a new `osd_memory_target` and the change is reflected.
