good morning, i am trying to understand ceph snapshot sizing. For example if i have 2.7 GB volume and i create a snap on it, the sizing says: (BEFORE SNAP) rbd du volumes/volume-d954915c-1dc1-41cb-8bf0-0c67e7b6e080 NAME PROVISIONED USED volume-d954915c-1dc1-41cb-8bf0-0c67e7b6e080 10 GiB 2.7 GiB (AFTER SNAP) rbd du volumes/volume-d954915c-1dc1-41cb-8bf0-0c67e7b6e080 NAME PROVISIONED USED volume-d954915c-1dc1-41cb-8bf0-0c67e7b6e080@snap01 10 GiB 2.7 GiB volume-d954915c-1dc1-41cb-8bf0-0c67e7b6e080 10 GiB 0 B <TOTAL> 10 GiB 2.7 GiB why the SNAP is 2.7 GB? is not going to be 0 GB in the beginning and only after the COW start doying its thing (copying original write blocks to snap before overwrite with new ones) it should grow? am i wrong? thank you. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
