Josh You'll need to use vinum as a volume manager first. Wouldn't recommend it at all on a mounted filesystem, this can give you alsorts of worries. I'd think about why you need to grow the volume, esp as any expansion of a RAID set will normally result in poor performance, unless you backup the data, rebuild the RAID set/filesystem and then restore the data. IE plan for any changes first. -- Martin On 6/21/06, Josh Endries <josh@endries.org> wrote: > > Hello, > > Has anyone out there successfully done an online expansion of a RAID > array in FreeBSD?
