Hi, Is it expected that swap on a thin volume should work? I'm guessing the answer is no because mkswap doesn't come with any sort of allocation request that would set the LE to PE mapping. What about a swapfile (on ext4 or XFS) onr a thin volume? In this case, I'd expect fallocate would set the LE to PE mapping, and it should work. But does it work for both paging and hibernation files? And what's the implication if the thin volume were to be snapshot?
