Hi, I experienced unexpected behaviour. When entirely deleting all rbds on a ceph pool (3/2) not only the used space decreased as expected but the total size of the pool increased significantly. IMHO it is caused by wrong calculations when osds are of slightly different sizes. Kind regards, --martin konold ppa.
