+Hello.
+
+What does this log mean?  It seems to tell" "success", then "openDirStream" fails, then "1 failed".  What failed?
+
+Context is in [todo/git annex repair: performance can be abysmal, huge improvements possible](https://git-annex.branchable.com/ikiwiki.cgi?do=goto&page=todo%2Fgit_annex_repair__58___performance_can_be_abysmal__44___huge_improvements_possible)

+    Deleted these local branches, which could not be recovered due to missing objects:
+    	refs/heads/master
+    	refs/heads/git-annex
+    You currently have refs/heads/master checked out. You may have staged changes in the index that can be committed to recover the lost state of this branch!
+    Successfully recovered repository!
+    Please carefully check that the changes mentioned above are ok..
+
+    git-annex: .git/annex/journal/: openDirStream: does not exist (No such file or directory)
+    failed
+    git-annex: repair: 1 failed
+
+The fact is: this repo is a plain git clone of a git annex repository.
+
+There is no `.git/annex` directory there before `git-annex-repair` is run.
+
+After it ran, there is a `.git/annex` directory with that content:

+
+Perhaps git-annex-repair gets confused when recovering a repository that is a plain git clone of a git annex repository?
+
+I did that because annexed objects are 1.7TB big here, so I wanted a local copy of pure git part only to perform repair of the repo, and propagate things somehow the objects at a later stage.
+
+I'll keep the repo lying around for a few days, maybe weeks, if some experiment or further feedback is needed.
+
+Thank you for your attention.
