My yardstick is currently "when a month goes by without anyone complaining it crashed on him" :) >It seems stable enough > for a number of applications today. This number is not so large. It seems to be easily crashed by rsync, for example (speaking from my own experience, and also some of my colleagues). > It's possible some of > the issues of memory requirements won't be fixable in 7.x, but I don't > think that's a given. I listened to some of Pawel's talks and devsummit brainstormings and I get the feeling *none* of the problems can be fixed in 7.x, especially on i386. I'm just asking for more official confirmation. This is not a trivial question, since it involves deploying systems to be maintained some years into the future - if ZFS will become stable relatively shortly, it might be worth putting up with crashes, but if not, there will be no near-future deployments of it.
