RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Vojtech Trefny 2021-11-23 09:44:37 UTC 
+++ This bug was initially created as a clone of Bug #2023883 +++

Description of problem:
Running through the gating process for vdo build vdo-6.2.6.7-14.el8 a failure with libblockdev/upstream_test_suite came up.

This is the text:
======================================================================
FAIL: test_stats (lvm_dbus_tests.LVMVDOTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/var/str/source/tests/lvm_dbus_tests.py", line 1644, in test_stats
    self.assertNotEqual(vdo_stats.saving_percent, -1)
AssertionError: -1 == -1

======================================================================
FAIL: test_stats (lvm_test.LVMVDOTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/var/str/source/tests/lvm_test.py", line 1621, in test_stats
    self.assertEqual(vdo_info.saving_percent, vdo_stats.saving_percent)
AssertionError: 100 != -1

This may be related to a similar failure that was encountered with the kernel component and posted about in #osci this morning.  BZ2023660 was opened for that issue.  The failures themselves are not the same, but the following message appeared in both:
** (process:20190): WARNING **: 15:19:19.087: The 'vdo' utility is not available

Hi,

Can not load vdo kernel module, and skip the testing, Is it expected ?

Yes, the test suite shouldn't fail just because the module is not available (or not compatible with the kernel).

These two versions work for me

# rpm -qq kmod-kvdo
kmod-kvdo-8.1.0.316-6.el9.x86_64
# uname -r
5.14.0-26.el9.x86_64

and generally if the kernel you are currently running isn't compatible with the installed version of kmod-kvdo, running "weak-modules --add-kernel --no-initramfs" should also help.

Yes, this build of kmod-kvdo should be available in the next set of nightly composes.  There was an AWS outage that prevented the build from being included sooner.
