Description Michael J. Kidd 2019-10-29 17:10:06 UTC
Description of problem:
Attempted to weight up a newly added osd node using:
# ceph osd reweight-subtree hostname 3.943
No peering or data movement occurred

Version-Release number of selected component (if applicable):
RHCS 3.3

How reproducible:
Every time

Steps to Reproduce:
1. Use reweight-subtree command


Actual results:
- no peering or data movement triggered

Expected results:
- peering / data movement

Additional info:
- Cluster had upmap entries, but it's unclear if upmap entries are a contributing factor

Comment 2 Michael J. Kidd 2019-10-30 16:11:08 UTC
Correction,
  The command issued was:

# ceph osd crush reweight-subtree hostname 3.943

I had a typo in my initial submission.

Note that the subtree items were reweighted according to 'ceph osd tree', however they never had PGs assigned to them as confirmed by no peering/recovery IO, also 'ceph osd df tree' showed 0 PGs per OSD on the reweighted OSDs.

Thanks!
