delete file from bucket

Error message

delete file %s from bucket

What it means

Wraps bkt.Delete in RemoveMark when deleting the mark file (deletion, no-compact, or no-downsample) that flags the block. It fires on object-storage errors while removing the already-verified mark, leaving the block still marked.

Solutions

1. Check bucket delete permissions
2. Retry after transient storage failures
3. Check for retention/legal-hold policies blocking deletes

When it happens
