On FreeBSD instances running within VMWare I have been able to add new disks without a reboot but, as I described below, have not found a way to get the operating system to detect a larger *existing* disk without a reboot. VMWare allows you to resize a disk on the fly. Obviously I'm only interested in the "grow the disk" scenario :-) I'm beginning to think a reboot is necessary, which is surprising! > On Dec 17, 2012, at 4:15 PM, Luke Bakken wrote: > > Hello everyone - > > I'm looking for a way to get FreeBSD 8 / 9 to detect that an already > existing disk has grown.
