In other topic you hammerd on fact and if someone ask you to deliver them its a stupid question. And about the dram error. I really hope you do use ecc memory in production which renders your scenario invalide. And even then its a claim made by you some random dude on a list.

You can loose data with any configuration or fs. so like in the compiler discussion. There is no perfect something in this world. It's always a tradeoff. with ZFS you have access to most advanced techniques and I believe that data is most safe with raidz3 as it can be. UFS cant match that and you have to rely on a raidcontroller which can screw up your data as well. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
