Thank you for your reply. > the object need only for OMAP data, not for actual data. I believe so. However, OMAP is set for an object, so I think that at least one object exists in PG. Below it appears that the OMAP exists even though the object does not exist. I feel it is strange. Is this correct? id used_mbytes used_objects omap_used_mbytes omap_used_keys -- ----------- ------------ ---------------- -------------- 6.2 0 0 86.14682674407959 298586 Thanks, Yuji _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
