OSD different sizes are used for different tasks. Such as cache. My concern is 4TB OSD, used as a storage pool. Place them engaged is not the same.
/Dev/sdf1 4.0T 1.7T 2.4T 42% / var / lib / ceph / osd / ceph-4 /Dev/sdd1 4.0T 1.7T 2.4T 41% / var / lib / ceph / osd / ceph-2 /Dev/sdb1 4.0T 1.9T 2.2T 46% / var / lib / ceph / osd / ceph-0 /Dev/sde1 4.0T 2.1T 2.0T 51% / var / lib / ceph / osd / ceph-3 /Dev/sdc1 4.0T 1.8T 2.3T 45% / var / lib / ceph / osd / ceph-1 For example, on /dev/sdd1 42%, and /dev/sde1 51%. They are 1 pool. Maybe there is an option which can be used to fill evenly OSD?

See: https://ceph.com/planet/ceph-osd-reweight/ http://docs.ceph.com/docs/master/rados/operations/control/#osd-subsystem It's probably not ideal to have OSD's of such different sizes on a node. ___ John Petrini NOC Systems Administrator // CoreDial, LLC // <http://coredial.com/> coredial.com // <https://twitter.com/coredial> Описание: Рисунок удален отправителем.

I have set up the repository ceph and created several pools on the hdd 4TB.
