Re: the reweight value of OSD is always 1

Hey,
it is normal for reweight value to be 1. You (with "ceph osd reweight OSDNUM newweight") or "ceph osd reweight-by-utilization" can decrease it to move some pgs out of that OSD.

Thing that usually differs and depends on disk size is "weight"

Hi Cephers!

The re-weight value of OSD is always 1 when we create and activate an OSD daemon.

I utilize ceph-deploy tool whenever deploy ceph cluster.

Is there a default reweight value of ceph-deploy tool?

Can we adjust the reweight value when we activate OSD daemon?

ID WEIGHT   TYPE NAME              UP/DOWN REWEIGHT PRIMARY-AFFINITY
-1 39.26390 root default
-2  9.81599     host ngcephnode01
 1  0.81799         osd.1               up  1.00000          1.00000
 3  0.81799         osd.3               up  1.00000          1.00000
 4  0.81799         osd.4               up  1.00000          1.00000
 5  0.81799         osd.5               up  1.00000          1.00000
 6  0.81799         osd.6               up  1.00000          1.00000



Thanks all!
