Yes! Your only 'problem' is having enough space to create a new volume in AFS where you can copy all that stuff in the old non-AFS storage. Once you have that stuff copied, you (and verified in some way) then you can use that old space for another AFS volume. ////jerry > > Thanks, > Mike > > -----Original Message----- > From: openafs-info-ad...@openafs.org [mailto:openafs-info-ad...@openafs.org] > On Behalf Of Lars Schimmer > Sent: Friday, April 30, 2010 2:41 PM > Cc: openafs-info@openafs.org > Subject: Re: [OpenAFS] Getting started with OpenAFS > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Mike Pliskin wrote: > > Dear all, > > > > First, let me state that I am a complete OpenAFS newbie.
