Description Pawan 2023-08-03 07:16:37 UTC 
Description of problem:
Partial recovery of objects support on EC pools will improve the recovery times.
We currently only support Partial recovery only on Replicated pools.

The feature needs to be expanded to also work with EC pools. This would improve the recovery times taken by EC pools.

Doc ref : https://docs.ceph.com/en/latest/dev/osd_internals/partial_object_recovery/ 


Version-Release number of selected component (if applicable):
6.0

How reproducible:
Always

Steps to Reproduce:
1. Deploy RHCS cluster, Create EC pools, write data.
2. Start flapping OSDs on the cluster.
3. Observe that for Replicated pools, Partial recovery is triggered, but not for EC pools.

Actual results:
No partial recovery in EC pools

Expected results:
Feature support for Partial recovery in EC pools.
