I just tried a bunch of combinations on a 3 x 11 raid60 configuration plus 3 global hotspares, and decided that letting the controller (LSI 9260-8i MegaSAS2) do it was easier all the way around. of course, with other controllerrs, your mileage may vary. and yes, megacli64 is an ugly tool to tame. with 3TB SAS drives, single drive failures rebuild in 12 hours, double failures in 18 hours. (failures forced by disabling drives via megacli) -- john r pierce N 37, W 122 santa cruz ca mid-left coast _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
