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 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

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?
For the record, we are still on version 17.2.3.
