My FreeBSD-4.9 setup uses one drive in "dangerously dedicated partition" where all of my partitions live in one slice: $ df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da0s1a 64462 37886 21420 64% / /dev/da0s1e 64462 4 59302 0% /tmp /dev/da0s1f 516062 6086 468692 1% /var /dev/da0s1g 2064302 1464672 434486 77% /usr /dev/da0s1h 10660096 720 9806570 0% /data procfs 4 4 0 100% /proc I almost run out of space during a buildworld, so I'd like to expand /usr from 2 GB to 4 GB by taking space away from /data. Since my filesystems will remain in the same slice, is it correct that I don't need to use fdisk(8)? So my procedure to do this is to recalculate the size/offset/cylinder settings for my partitions "g" & "h", change those settings via disklabel(8), then use growfs(8) on /dev/da0s1g? Seems simple enough, and the data on /usr should be preserved, correct? But will /dev/da0s1h be okay? Is editing the disklabel enough? Or do I need to reformat the partition --- and, if so, how? I'm not too comfy using newfs(8) directly. Can I just run "newfs /dev/da0s1h" after running the growfs(8) command and it will use the disklabel settings? Or can I be a wuss and use /stand/sysinstall? :-) Any suggestions are appreciated, thanks in advance!
