It depends on the environment, I'm afraid. We don't have any problems with it anymore since 8.3 > 2. Is there anyone that installed it in prod and can give some > feedback about stability, config? Again, it depends on the use-case. We do some hosting of web-pages with it (a couple of hundred home-directories with a couple of hundred GB of data all together. Some (Much?) also depends on the hardware used. > 3. from all the mails about reccomendations I've seen, is someone in > fbsd-team taking the reccomendations and putting them somewhere in a > one-document that describes all the suggestions rather than mailing > lists? There is https://wiki.freebsd.org/ZFSTuningGuide =46rom time to time, the list gets postings like yours, with people nodding and agreeing that someone should write it all up....
