I just read in another post about disklayout _____________________________________________________________ According to the manual as of 9.0-RELEASE the default fragment and block sizes for newfs are 4k and 32k, so provided your partitions/slices are 4k aligned everything Should Just Work. Before 9.0 fragments and blocks were 2k and 16k which doesn't play so well with 4k drives. ____________________________________________________________
I wrote that. It's only relevant if you have recent disks with 4k hardware blocks. If you have, you ought to use 4k/16k filesystems whatever your OS rev. If you haven't, it doesn't matter. If it's not broken, don't fix it, is a very good principle.
I started thinking about the choices I have for upgrading my running 8.3 systems. I'm aware about of the procedure with freebsd-upgrade and rebuilding all ports according to man portmaster. Would you just do the upgrade or would you consider reinstalling? Would it be beneficial to make a fresh installation?
Like Erich Dollansky, I prefer to upgrade via source, but that's because I like tweaking my system in mildly non-standard ways. (More a habit than a necessity, but I've been doing it since 6th Edition Unix. :-) If you're running a vanilla install with GENERIC kernel freebsd-upgrade is probably going to be quicker even if you've got a multicore monster to recompile on. Just make sure you can reinstall if something goes bad during the upgrade and *back up anything vital first*.
