Andreas, Since you're able to reproduce, are you able to give https://review.whamcloud.com/c/fs/lustre-release/+/62095 a try? Not sure if it's directly relevant but it's closely related code.

It has a simple reproducer that seems to show some kind of real issue. https://github.com/lustre/lustre-release/issues/16 On Feb 6, 2026, Anil Mahadev Misal <[email protected]> wrote: > > Dear Team, > > I am facing error -14 while pip installation.
