I've been playing with 8.0 zfs on low end machines(laptops with 768MB-1GB RAM and just one disk device). I have successfully made them boot off of ZFS using gpt, this is not mentioned in ZFSOnRoot. I used the guide found here: http://blogs.freebsdish.org/lulf/category/freebsd/ Also still requires manually recompiling loader with ZFS support. Shouldn't this made trhe default in 8.0? I had a panic while doing a make clean in the openoffice port after compilation due to kmem exhaustion using the tuning suggested in the Tuning Guide; solved by using these: vm.kmem_size="384M" vm.kmem_size_max="384M" vfs.zfs.arc_max="40M" vfs.zfs.vdev.cache.size="5M" this is on an i386 laptop with 768 MB RAM, I should experiment a little with cache.size and arc_max too... On a 1GB RAM laptop(it's an EeePC labelled 904HA, has a 160GB disc) I'm using slughtly higher values with success for now, but I've installed this just a few days ago and have not made any tests. The last thing I noticed is the knownproblems wiki reports swapping on zfs' zvols is not working. I have not stress tested this to the limit, but my systems are successfully working with zvols as the only swapping device and actively swaping to it. What could be a good way to stress test his to the limit? hope these information helps someway. I'd like to test ZFS on some serious hardware with serious load, but I haven't had the chance at work for the time being. -- Guido Falsi <m...@madpilot.net> _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
