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.

Just like in the rhel8.5 version bug 1996227, only the 8.00k logical scenario actually matches. The 3.00k gets rounded WAY up by the VDO create cmd and the 10.00k gets rounded down by the vdo create cmd. So, neither of these are the fault of the lvm conversion tool.


SCENARIO - [small_vdo_logical_size_convert_to_lvm]
Test the basic conversion of a small (3k, 8k, 10k) logical sized existent vdo volume to lvm (1996227|2005006)

Creating VDO lvm_import_vdo_sanity
      Logical blocks defaulted to 486134360 blocks.
      The VDO volume can address 1 TB in 929 data slabs, each 2 GB.
      It can grow to address at most 16 TB of physical storage in 8192 slabs.
      If a larger maximum size might be needed, use bigger slabs.
