  • Type: Bug Fix

  • Impact: Normal

  • Reference to related issue (URL): none

  • How was this pull request tested? Ran rear mkrescue and rear recover on Ubuntu 18.04.2 LTS server before and after patching. Verified fix works as intended.

  • Brief description of the changes in this pull request:

This PR corrects a mapping error when TCG Opal 2 self-encrypting disks were present but had to be excluded due to a non-existent disk during recovery. This exclusion was not handled properly.

(Edit: dropped second change)

I assume this issue hapens only when you are in MIGRATION_MODE
because the apply_layout_mappings function is only called there.

I would like to better understand what actually goes on on your
particular system because 'an unmapped disk was present' looks like
things are wrong because - as far as I can imagine offhandedly - there
must not be any unmapped disk left, see my comments in the
apply_layout_mappings function that show an example where
the _REAR*_ string disk _REAR3_ is left which is then
correctly detected and reported by "Step 3".

could you also have a look here and review it?

Do you think we can add it to ReaR 2.5?
