Environment:

  • git-annex running in WSL (ext4)
  • Special remote on NTFS filesystem

Issue:

Files in special remote with exporttree/importtree enabled fail to download during fsck operations. The issue affects only some files, with no clear pattern between affected and unaffected files (occurs with both binary and text files). Steps to reproduce:

  • Set up git-annex repository in WSL (ext4)
  • Configure special remote on NTFS with exporttree/importtree
  • Run git annex fsck on files
  • Some files fail with download error

Verification:

Direct comparison shows files are identical:

diff ~/mydir/work/info/templates/form.svg .git/annex/objects/qg/Vk/SHA256E-s2258--0faa4a5b2bbb98665d79741ce8e88aa0fe9fb526ba9990bc51b830e1d767c3fe.svg/SHA256E-s2258--0faa4a5b2bbb98665d79741ce8e88aa0fe9fb526ba9990bc51b830e1d767c3fe.svg

(outputs nothing, files are identical)

Current behavior:

git annex fsck info/templates/form.svg -f specrepo
failed to download file from remote
failed
(recording state in git...)
fsck: 1 failed

git annex get info/templates/form.svg -f specrepo
get info/templates/form.svg (from specrepo...)
   file content has changed
failed
get: 1 failed

Expected behavior:

FSck should complete verification successfully. All files should download and verify correctly

Additional notes:

  • Issue appears to be related to filesystem differences (NTFS vs ext4)
  • Problem affects only some files, while others work correctly
  • No clear pattern between affected and unaffected files (occurs with both binary and text files)
  • Standard remediation steps (fsck, fix, reinject) do not resolve the issue
