So many people misunderstand the ZIL SLOG, including the guy you are responding to.
I think most posts on the internet about the ZIL SLOG do not explain it correctly and thus a large number of people misunderstand it.
- magicalhippo 5y agoYes it took me some time to fully grasp how the ZIL and SLOG worked and how it is not a cache. There was some work done[1] on proper write-back cache for ZFS by Nexenta several years ago, but it seems it either stalled or there was a decision to keep it in-house as it hasn't made its way back to OpenZFS.
