Description

if in Ceph with VDO OSD add more than 512Gb of data, RAW space start wrong calculating.
I think in Ceph implemented recalculating pool used space after each 512Gb and after this value RAW space for VDO dont calculate right.

Fedora 31
Ceph version 14.2.7
For mote details see screenshots.
On screenshots 1 OSD with VDO, and Ceph cluster with replication factor 1.
