How is the host being "rebuilt"? Depending on the CRUSH rule, if the host's OSDs are all marked destroyed and then re-created one at a time with normal weight, CRUSH may decide to put a large number of PGs on the first OSD that is created, and so on, until the rest of the host's OSDs are available to take those OSDs.
