It can be done but it's not easy and not pretty. You'll have to rewrite the partition scheme to grow *only* the last partiti= on and then use growfs on the last partition to zero the new inodes within = its newly defined range. You'll of course need to boot from another medium to do this. I usually use DruidBSD for this: DruidBSD-1.0b1.iso (a tiny 23.5MB ISO that you can write to thumb disk with dd or burn to cd; = either works fine) Boot from it and use the tools like "disklabel -e /dev/yourdisk" But=85 be extremely careful and do your mathematics! I know this isn't a complete step-by-step guide, but I wanted to get the an= swer out there that this is possible and it's a known quantity, but it can = be dangerous if you get the math wrong when editing the disklabel positions= , for example. If you can get that part right, the rest is easy (growfs). --=20 Devin On Dec 17, 2012, at 4:15 PM, Luke Bakken wrote: > Hello everyone - >=20 > I'm looking for a way to get FreeBSD 8 / 9 to detect that an already > existing disk has grown.
