Re: [ceph-users] Undersized pgs problem

Vasiliy, Your OSDs are marked as 'down' but 'in'. "Ceph OSDs have two known states that can be combined. *Up* and *Down* only tells you whether the OSD is actively involved in the cluster. OSD states also are expressed in terms of cluster replication: *In* and *Out*. Only when a Ceph OSD is
