Description skanta 2021-04-14 05:55:16 UTC

Description of problem: If the limit variable count is greater than the  vendor/model/path/rotational device count, all the existing devices in the cluster are configuring as OSD's.

For example:

In the below example I am providing the limit as 6 but in my cluster, there are only 5 devices that exist.


[ceph: root@magna045 ~]# cat osd_spec.yml 
service_id: osd_spec_hdd
placement:
  host_pattern: '*'
data_devices:
  rotational: 0
  limit: 6
db_devices:
  model: SAMSUNG MZ7LH7T6
[ceph: root@magna045 ~]# 


If we are trying to configure with the above osd_spec.yml, osd's are getting configured 5.There is no information that why we are adding 5 instead of 6.

[ceph: root@magna045 ~]# ceph orch apply osd -i  osd_spec.yml  --dry-run
WARNING! Dry-Runs are snapshots of a certain point in time and are bound 
to the current inventory setup. If any on these conditions changes, the 
preview will be invalid. Please make sure to have a minimal 
timeframe between planning and applying the specs.

Removing [RFE], cause (1) this is in-flight already and I'd like to have this in 5.1. (2) One can interpret this as a user experience bug.
