Here's one horror story of mine - ZFS taking over 20 minutes to flag a drive as faulty, with the entire pool responding so slowly during those 20 minutes that it crashed six virtual machines running off the pool: http://www.opensolaris.org/jive/thread.jspa?messageID=369265񚉱
There are some performance tweaks mentioned in that thread, but I haven't been able to test their effectiveness yet, and I'm still concerned. A pool consisting of nothing but three way mirrors should not even break a sweat when faced with a single drive problem. When you're implementing what's sold as the most advanced file system ever, billed as good enough to obsolete raid controllers, you don't expect to be doing manual tweaks just so it can cope with a drive failure without hanging the entire pool. ZFS has its benefits, but if you're not running it on Sun hardware you need to do a *lot* of homework. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
