      This is supposedly solved for some time and needs just restesting - although likely the patch is part of usptream package - and backport to RHEL-8 is not in question - as it cannot be qualified as a security bugfix - so bug will likely be closed as having a  next-release  (RH9).

      Description of problem:

      This appears similar/related to bug 1996227.

      1. 30T

      SCENARIO - large_vdo_logical_size_convert_to_lvm: Test the basic conversion of a large (4t) logical sized existent vdo volume to lvm (1996227)
      vdo create --force --name lvm_import_vdo_sanity --vdoLogicalSize 30T --device /dev/sda1
      Creating VDO lvm_import_vdo_sanity
      The VDO volume can address 1 TB in 998 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.
