New OverlayUnmountError with 5.21 lxd
Metadata
Current evaluation
Overlay-based spread tests fail to unmount under LXD 5.21 with exit status 32; the open, unlabelled report has only an automated Jira comment and no diagnosis.
Suggested action: needs triage
Reason: The report identifies two failing tests and logs showing five unmount attempts ending in status 32, so the regression is concrete. However, reproduction and environment contain only '.', no mount diagnostics are supplied, and the sole comment is automated; the lack of labels or maintainer response leaves the issue untriaged. Commit 90bc9b34/PR #694 confirms LXD 5.21/candidate is relevant but does not establish that the failure was fixed.
