All of the disks in my cluster are identical and therefore all have the same weight (each drive is 2TB and the automatically generated weight is 1.82 for each one).
Would the procedure here be to reduce the weight, let it rebal, and then put the weight back to where it was? -- Kevin Weiler IT IMC Financial Markets | 233 S.

You’d think it would be less…. I would think an overperforming disk should (desirably) cause that case,right?

Try running "ceph osd crush reweight osd.<##> 1.0. If that doesn't do the trick, you may want to just out that guy. I don't think the crush algorithm guarantees balancing things out in the way you're expecting. --Greg On Tue, Nov 5, 2013 at 11:11 AM, Kevin Weiler <kevin.wei...@imc-chicago.com<mailto:kevin.wei...@imc-chicago.com>> wrote: Hi guys, I have an OSD in my cluster that is near full at 90%, but we're using a little less than half the available storage in the cluster.
