Does anyone happen to have expertise/pointers on how ZFS' ARC interacts with Linux disk caching currently when using ZFS-on-Linux? It seems like the ARC space shows up as "used" despite being in a similar category of "made available if needed" - is that correct?
Is data in the ARC double-cached by Linux's disk caching mentioned in the post? If so, is it possible to disable this double-caching somehow?
