Assuming I understand it correctly: "pg_upmap_items 6.0 [40,20]" refers to replacing (upmapping?) osd.40 with osd.20 in the acting set of the placement group '6.0'. Assuming it's a 3 replica PG, the other two OSDs in the set remain unchanged from the CRUSH calculation. "pg_upmap_items 6.6 [45,46,59,56]" describes two upmap replacements for the PG 6.6, replacing 45 with 46, and 59 with 56. Hope that helps.
