Subject: mgr/module: adjust osd_weight min step to .005
X-Git-Tag: v12.2.2~44^2~8
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=91b84cb24466f84ce3e189e08f8cba1e2900a4cc;p=ceph.git

mgr/module: adjust osd_weight min step to .005

That should be ~1 PG or less on average; no real sense it taking a
step smaller than that!
