True, but if things get out of order for some reason, then you have a mess. > Here are my notes: > http://www.wonkity.com/~wblock/docs/html/disksetup.html Thanks, already read that and bookmarked it quite a while ago. ___ 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"

Found the archive, didn't really help. However, I did rewrite both boot areas and that solved the problem: gpart bootcode -b /boot/pmbr ada3 gpart bootcode -p /boot/gptboot -i 1 ada3 So apparently the 9.1 installer wipes out at least the boot code in partition 1. Since the spinner went a few notches, I suspect the primary boot block is ok, but it crashed when it can't execute the gptboot code. ___ 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"

What did it say? When doing the 9.1 install, I selected the disk and had to assign the partitions to the various filesystems. AFIK, I did not otherwise modify the filesystems. Does the 9.1 install process trash the boot areas? My gpart setup was: clean up (delete) the original partitions gpart destroy ada3 These two steps can be replaced with gpart destroy -F ada3 gpart create -s GPT ada3 gpart bootcode -b /boot/pmbr ada3 gpart add -t freebsd-boot -i 1 -s 512K -l gptboot ada3 gpart bootcode -p /boot/gptboot -i 1 ada3 I do the bootcode in one step: gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada3 gpart add -t freebsd-ufs -a 4K -b 1M -s 4G -i 2 -l fbsdroot ada3 # / gpart add -t freebsd-swap -a 4K -s 2G -i 3 -l fbsdswap ada3 # swap gpart add -t freebsd-ufs -a 4K -s 2G -i 4 -l fbsdvar ada3 # /var gpart add -t freebsd-ufs -a 4K -s 2G -i 5 -l fbsdtmp ada3 # /tmp gpart add -t freebsd-ufs -a 4K -i 6 -l fbsdusr ada3 # /usr It's not necessary to use partition numbers with "add", gpart will just use the next one available.
