Newer kernels are much more strict about swapping extents to avoid filesystem corruptions that can occur as a result inode fork offset mismatchs. If you trace the fsr run with: # trace-cmd record -e xfs_swap\* xfs_fsr ..... And then dump the trace to a file via: # trace-cmd report > some_output_file.txt and attach some_output_file.txt then I can probably tell you exactly why the request to swap extents is failing. > If you can reproduce this problem, could you tell me by which kernel > or xfsprogs version this will be fixed?

I think you've got that the wrong way around - it's the older versions of XFS that are unsafe as they can silently corrupt files, not the newer kernels that issue a warning after detecting this problem and hence return an error...
