Hello Ceph Users,
We have added more ssd storage to our ceph cluster last night. We added 4 x 1TB
drives and the available space went from 1.6TB to 0.6TB ( in `ceph df` for the
SSD pool ).
I would assume that the weight needs to be changed but I didn't think I would
need to? Should I change t
Thanks for the reply! - it ended being that the HDD pool in this server is
larger than the other servers. This increases the server's weight and therefore
the SSD pool in this server is affected.
I will add more SSDs to this server to keep the ratio of HDDs to SSDs the same
across all hosts.

Glen,
Correction...looked at the wrong column for weights, my bad...
I was looking at the wrong column for weight. You have varying weights,
but the process is still the same. Balance your buckets (hosts) in your
crush map, and balance your osds in each bucket (host).

Glen,
It appears you have 447G, 931G, and 558G disks in your cluster, all with a
weight of 1.0. This means that although the new disks are bigger, they are
not going to be utilized by pgs any more than any other disk.
I would suggest reweighting your other disks (they are smaller), so that
you b
