Hi Dan, indeed I'm trying to balance the PGs.
In order to ensure Ceph cluster operations I used OSD reweight, means some specific OSDs are not with reweight 0.8 and 0.9 respectively. Question: Can I upgrade to Ceph 14.2.8 w/o resetting the weight to 1.0? Or should I cleanup this reweight first, the upgrade to 14.2.8 and enable balancer as last?
