Even if it was pure concatenation. No, an LVM2/VxFS is needed. Also, shops that can afford SAN and high end RAID tend to be able to provision temp space to store media while they expand and re-create volumes. ~BAS On Wed, 2007-06-27 at 20:21 +1000, Norberto Meijome wrote: > On Wed, 27 Jun 2007 17:07:32 +0700 (ICT) > Olivier Nicole wrote: > > > > that's what a volume manager (such as LVM2 in linux, Veritas Vol Mgr , and > > > vinum (I think) in FBSD 4 ) do - they abstract the hardware storage layer. > > > > That is hardware RAID. > > yes, i realise you mentioned it .
