Yes, I believe so. That is, if you have files sharing extents (like if you de-duplicated them or did a "cp --reflink=always") and defrag touches those files, it will undo the extent sharing. > Also, will autodefrag compress files automatically, as mount option > enforces (compress-force=zstd:3)? Yes. > Any suggestions welcome. If you're not relying on extent sharing then I'd think that automated defrag is okay. Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
