XFS is not copy on write.
- vetinari 7y agoXFS has supported reflinks for some time already, just the deduplication is kind of experimental. Supporting reflinks is actually more, than can be said about ZoL (see zfsonlinux#405).
- zepearl 7y agoI think that you're both right - under normal conditions XFS not CoW, but when using the reflink option it does use CoW => kind of a mix.
