Hi,
Ceph storage on each disk in the cluster is very unbalanced. On each
node, the data seems to go to one or two disks, while other disks
are almost empty.
I can't find anything wrong from the crush map, it's just the
default for now. Attached is the crush map.
Have you been reweight-ing osds? I went round and round with my cluster
a few days ago reloading different crush maps only to find that it
re-injecting a crush map didn't seem to overwrite reweights.
Take a look at `ceph osd tree` to see if the reweight column matches the
weight column.
Note: I'm new at this. This is my experience only, with 0.48.1, and may
not be entirely correct.
