[SPDK] Re: spdk doesn't seem to recognize the drive in container with unprivileged mode

Hi,

Saw your note on Slack, that's probably a better place to have the discussion.  Will get back to you over there shortly...

Thanks!

    Hi Folks,

    I am trying to run k8s pod with unprivileged mode but spdk doesn't seem to
    recognize the drive but the vfio device seems to be present on the pod.

    nvme.c: 609:spdk_nvme_probe_internal: *ERROR*: NVMe ctrlr scan failed
    bdev_nvme.c:1766:spdk_bdev_nvme_create: *ERROR*: No controller was found
    with provided trid (traddr: 0000:88:00.0)

    $ kubectl exec -it pod-0 /bin/bash
    $ ls -ld /dev/vfio/91
    crw------- 1 root root 241, 10 Jul 16 14:44 /dev/vfio/91
    $ readlink /sys/bus/pci/devices/0000\:88\:00.0/iommu_group
    ../../../../../../kernel/iommu_groups/91

    Note:- with privilege mode there are no issues
