Some thoughts about upgrading from 8.3 to 9.1
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 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?

Would it be beneficial to make a fresh installation? let me phrase it this way: I upgrade always via source but I am prepared to hit a wall between. The number of walls are very low meanwhile. The advantage of a normal upgrade via sources are so many that I always risk it. But I make sure that I have the option of re-installation at hand.

Followed by pkg-add -r for all my ports. I even use the pkg versions of dependents that are required by php because I have to recompile the php port to turn on the apache module and turn off everything else. This way I only compile php and not its dependents. I have the pkg_add -r commands embedded in a script that automates the whole procedures. The installed packages stay at whatever version they are at as of new OS Release time. I do not update running packages during the life of the installed OS Release. Been doing this since Release 3.0 without any problems. Install process takes about 30 minutes. Time for downloading disc1.iso and burning it is not included in that 30 minutes. ___ 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

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.

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*. ___ 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

If you have, you ought to use 4k/16k filesystems whatever your OS rev. That should be 4k/32k. As man newfs says: The optimal block:fragment ratio is 8:1. Other ratios are possible, but are not recommended, and may produce poor results. ___ 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
