Required package libblockdev-nvme not installed on EL9

[myllynen]

Perhaps the role should install libblockdev-nvme as on RHEL 9 I saw this error without manually installing it:

TASK [redhat.rhel_system_roles.storage : Manage the pools and volumes to match the specified state]
...
fatal: [10.10.10.10]: FAILED! =>
    changed: false
    module_stderr: |4-

        ** (process:8840): WARNING **: 12:38:45.660: failed to load module nvme: libbd_nvme.so.2: cannot open shared object file: No such file or directory

Thanks.

I've added the dependency on #383, but the nvme plugin is optional dependency in blivet, so we should also try to find out why is it a critical error here.

[richm]

@myllynen is #382 (comment) the full, entire error message?
I'm running https://github.com/linux-system-roles/storage/blob/main/tests/tests_swap.yml#L44 except that I have changed it to use type: lvm. Then I run like this:

tox -e qemu-ansible-core-2.15 -- --image-name rhel-9-2 --log-level debug tests/tests_swap.yml 2>&1 | tee output

This is the output:

fatal: [/home/rmeggins/.cache/linux-system-roles/rhel-9-2.qcow2]: FAILED! => {
    "changed": false,
    "rc": 1

As you can see - the libbd_nvme.so.2 part is just a WARNING - the actual error is in the python code traceback:

  File "/tmp/ansible_blivet_payload_whkias3u/ansible_blivet_payload.zip/ansible/modules/blivet.py", line 711, in _get_device_id
AttributeError: 'NoneType' object has no attribute '_device'

This is the "real" problem.

[myllynen]

Thanks, indeed it was the same for me. Perhaps the warning could be ignored, though libblockdev-nvme adds only 270k after installing the other pre-req packages.

[richm]

I would like to find some way to suppress the WARNING and CRITICAL errors - they just add noise and make debugging difficult.

That needs to be fixed in libblockdev, blivet will then redirect the error messages to its log file instead of having these printed on stderr.
