Doc Type: Known Issue
Doc Text:
.The `filestore-to-bluestore` playbook does not support the`osd_auto_discovery` scenario {storage-product} 4 deployments based on `osd_auto_recovery` scenario can't use the `filestore-to-bluestore` playbook to ease the `BlueStore` migration. To work around this issue, use `shrink-osd` playbook and redeploy the shrinked OSD with `osd_objectstore: bluestore`.

Description Vasishta 2020-09-22 15:25:05 UTC 
Description of problem:
When osd_auto_discovery is set to true and OSDs are migrated from filestore to bluestore, SSDs(NVMe in this case) are omitted when bluestore OSDs are created.

Version-Release number of selected component (if applicable):
ceph-ansible-4.0.31-1.el7cp.noarch
ceph-4.1-rhel-8-containers-candidate-73222-20200911013858
ceph-common-14.2.8-108.

How reproducible:
Always (2/2)

Steps to Reproduce:
1. Configure RHCS 3.x cluster with filestore OSDs
2. Upgrade cluster to 4.x 
3. Migrate flestore OSDs to bluestore

Actual results:
SSDs(NVMe in this case) are omitted when bluestore OSDs are created.

Expected results:
NVMe OSDs should be part of OSD creation

Is this a regression? If not, why is it a proposed blocker?

Hi Yaniv,

> Is this a regression? If not, why is it a proposed blocker?

Yes, I think that this is a Regression, 
I do not know how to add the keyword while filing the BZ, I'm adding it now after uploading the suitable logs.
