Glenn, can you tell me which of those numbers, if any, can be changed after a newfs has been done and the file system well occupied with data? (The lousy sysinstall disk labeler wiped out several of my disk labels and I restored them with zeroes in those fields of the disk label. It worked OK, but I'm guessing it only worked because the "bsdlabel" defaults were the same as they were when I first did "bsdlabel...; newfs...". If defaults had changed or I used non-default values the first time, I'd have been SOL, right? Or do those values just serve as optimization/tuning values for the kernel?) _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
