Description of problem: - When installing ODF 4.9 with internal local storage using LSO, the creation of the StorageSystem cannot move forward because there are no available devices for the ODF cluster. Version-Release number of selected component (if applicable): - OpenShift 4.9.29 - ODF 4.9.6 - LSO local-storage-operator.4.9.0-202204211825 How reproducible: - All the time on user's environment Steps to Reproduce: 1. Present a device with multiple paths to the storage nodes 2. Device gets visible through multipath as mpath device (multipath -ll) 3. Create a StorageSystem using local storage devices 4. In step 2, "create logical volume set", the filter gets zero matches because `mpath` device is listed as invalid Actual results: - Cannot install ODF with local storage using LSO Expected results: - Be able to complete the installation Master Log: Node Log (of failed PODs): PV Dump: PVC Dump: StorageClass Dump (if StorageClass used by PV/PVC): Additional info:
Historically, LSO supported all local block devices, regardless of the actual backend and transport protocol. We would like to continue with that and fix multipath, it's up to ODF if they want to consume such devices for Ceph. It's up to the node admin to create such block devices and keep them working using standard RHEL / RHOCS tools and their support. Using EMC CSI driver, as suggested by Greg above would be probably a better option.
