I've added an error whenever any disk cannot be found. Previously the node would not report an error if at least one disk was successfully found.

Description of problem: Need a clear event for local storage operator when not finding the device defined in localvolume Version-Release number of selected component (if applicable): quay.io/openshift-release-dev/ocp-v4.0-art-dev:v4.2.0-201908181300-ose-local-storage-operator How reproducible: 100% Steps to Reproduce: 1. Installed local storage operator in OCP 2. Created localvolume instance to deploy local storage provider 3. Updated the localvolume instance with a non-exist device (/dev/loop10 does not exist) $ oc get localvolume local-disks -ojson|jq .spec.storageClassDevices [ { "devicePaths": [ "/dev/loop1", "/dev/loop2", "/dev/loop10" ], "fsType": "xfs", "storageClassName": "local-sc", "volumeMode": "Filesystem" }, { "devicePaths": [ "/dev/loop3", "/dev" ], "fsType": "ext4", "storageClassName": "local-ext4", "volumeMode": "Filesystem" } ] 4. Check the event Actual results: 1. The event only said "found empty matching device list", this is not clear. 2. On all worker nodes, /dev/loop10 does not exist, but there is only one event from one worker node. $ oc describe localvolume|grep Events -A 12 Events: Type Reason Age From Message ---- ------ ---- ---- ------- Warning ErrorFindingMatchingDisk 22m local-storage-diskmaker ip-10-0-152-60.us-east-2.compute.internal - found empty matching device list Warning ErrorFindingMatchingDisk 22m local-storage-diskmaker ip-10-0-173-82.us-east-2.compute.internal - found empty matching device list Normal FoundMatchingDisk 21m local-storage-diskmaker ip-10-0-133-153.us-east-2.compute.internal - found matching disk loop3 Warning ErrorFindingMatchingDisk 19m local-storage-diskmaker ip-10-0-173-82.us-east-2.compute.internal - found empty matching device list Warning ErrorFindingMatchingDisk 19m local-storage-diskmaker ip-10-0-152-60.us-east-2.compute.internal - found empty matching device list Normal FoundMatchingDisk 16m local-storage-diskmaker ip-10-0-133-153.us-east-2.compute.internal - found matching disk loop3 Warning ErrorFindingMatchingDisk 15m local-storage-diskmaker ip-10-0-173-82.us-east-2.compute.internal - found empty matching device list Normal FoundMatchingDisk 15m local-storage-diskmaker ip-10-0-152-60.us-east-2.compute.internal - found matching disk loop3 Warning ErrorFindingMatchingDisk 12m local-storage-diskmaker ip-10-0-173-82.us-east-2.compute.internal - found empty matching device list Warning ErrorFindingMatchingDisk 9m10s local-storage-diskmaker ip-10-0-173-82.us-east-2.compute.internal - found empty matching device list Expected results: The event can describe which node does not have which device.
