Umh Taking a look to your computation I think the ratio OSD/Overhead it's really about 1.1Gb per OSD. Because I have 9 NVMe OSD alive right now. So about 9.5Gb of overhead. So I guess this is just it's right behaviour. Fine! Il 02/03/2018 15:18, David Turner ha scritto: [1] Here is a

I don't care of get back those space. I just want to know if it's expected or not. Because I run several rados bench with the flag |--no-cleanup| And maybe I leaved something in the way. Il 02/03/2018 11:35, Janne Johansson ha scritto: 2018-03-02 11:21 GMT+01:00 Max Cuttins
