Description Manoj Katari 2023-10-30 14:01:16 UTC

During RHOSP 17.1+Ceph deployment, overcloud deploy fails to set the 'target_size_ratio' 

These are pool related parameter passed to the overcloud deploy command.

[stack@undercloud-1 ~]$ cat /home/stack/templates/ceph-pools.yaml
parameter_defaults:
 CephPools:
  - name: volumes
   target_size_ratio: 0.4
   application: rbd
   rule_name: replicated_rule
  - name: images
   target_size_ratio: 0.1
   application: rbd
   rule_name: replicated_rule
  - name: vms
   target_size_ratio: 0.3
   application: rbd
   rule_name: replicated_rule


But pools are not set with 'target_size_ratio'

[tripleo-admin@overcloud-controller-0 ~]$ for pool in volumes vms backups images; do echo -e "\n####Pool: $pool"; sudo cephadm shell -- ceph osd pool get $pool target_size_ratio; done

Comment 1 Manoj Katari 2023-10-30 14:04:55 UTC

After the updates to pool creation task https://review.opendev.org/c/openstack/tripleo-ansible/+/884555/20/tripleo_ansible/roles/tripleo_cephadm/tasks/pools.yaml

Which will not use ceph_pool python module and runs the pool creation command direclty.

The command run at https://opendev.org/openstack/tripleo-ansible/src/branch/stable/wallaby/tripleo_ansible/roles/tripleo_cephadm/tasks/pools.yaml#L28 doesn't support the option target_size_ratio.

Hi Saumik,

This patch sets `target_size_ratio` during pool_creation.

As a WA for z3, it can be manually set after the pool creation using the command below , you can refer [1] for more details.

#sudo cephadm shell -- ceph osd pool set <pool-name> target_size_ratio <ratio_value>
