Hello,
What I have used to rebalance my cluster is:
ceph osd reweight-by-utilization
we're using a small Ceph cluster with 8 nodes, each 4 osds. People are
using it
through instances and volumes in a Openstack platform.
We're facing a HEALTH_ERR with full or near full osds :
cluster 5942e110-ea2f-4bac-80f7-243fe3e35732
health HEALTH_ERR 1 full osd(s); 13 near full osd(s)
