Hello, My apologies if this has been answered previously but by attempt to find an answer have failed me. I am trying to determine the canonical manner for determining how much storage space a cephfs snapshot is consuming. It seems that you can determine the size of the referenced data by pulling the ceph.dir.rbytes attribute for the the snap directory, however there does not seem to be an attribute which indicates the storage the snapshot it's self is consuming: getfattr -d -m - daily_2021-10-07_191702 # file: daily_2021-10-07_191702 ceph.dir.entries="17" ceph.dir.files="0" ceph.dir.rbytes="6129426031788" ceph.dir.rctime="1633653849.686409000" ceph.dir.rentries="132588" ceph.dir.rfiles="97679" ceph.dir.rsubdirs="34909" ceph.dir.subdirs="17" I have found in the documentation references to the command "ceph fs subvolume snapshot info" which should be able to give snapshot size in bytes for a snapshot of a subvolume, however we are not using subvolumes. If we assume a cephfs volume "volume" with a top-level directory "directory" and an associated snapshot "snapshot": volume/directory/.snap/snapshot What is the best way to determine the size consumed by snapshot?
