I had forgotten that the snapshot contains data that was removed. Now everything makes sense. Thank you very much! Em qua., 14 de ago. de 2024 às 11:53, Anthony D'Atri <aad@dreamsnake.net> escreveu:

Good morning everyone!
I am confused about the listing of the total amount used on a volume. It says that more than the amount provisioned is being used.
The command shows 710GB of changes since the snapshot was taken, added to the 404GB currently used by the parent. The snapshot by nature retains data that has been changed or deleted in the parent.
The image contains a snapshot. Below is the output of the "rbd du" command:
user@abc2:~# rbd info osr1_volume_ssd/volume-6e5f90ac-78e9-465e-8705-a4d476ebc019 rbd image 'volume-6e5f90ac-78e9-465e-8705-a4d476ebc019': size 1000 GiB in 256000 objects order 22 (4 MiB objects) snapshot_count: 1 id: 3ec2fef4cd0ad8 block_name_prefix: rbd_data.3ec2fef4cd0ad8 format: 2 features: layering, exclusive-lock, object-map, fast-diff, deep-flatten op_features: flags: create_timestamp: Fri Jan 5 22:48:45 2024 access_timestamp: Wed Aug 14 10:46:06 2024 modify_timestamp: Wed Aug 14 10:47:02 2024 user@abc2:~# rbd du osr1_volume_ssd/volume-6e5f90ac-78e9-465e-8705-a4d476ebc019 NAME PROVISIONED USED volume-6e5f90ac-78e9-465e-8705-a4d476ebc019@snapshot-23af41b0-ca7b-45df-991f-ffbe95512dbe 1000 GiB 710 GiB volume-6e5f90ac-78e9-465e-8705-a4d476ebc019 1000 GiB 404 GiB <TOTAL> 1000 GiB 1.1 TiB
In this case, is that really the case or is it some kind of BUG?
