I think a large number of people in datacenters are using hardware RAID these days, and if they don't need that, then the simplicity of the graid3/gmirror/gstripe tools covers it. gvinum isn't as easy to use, and there's been reports of problems with it, so people who use it in datacenters will find something that at least *appears* more stable. I've found gmirror and gstripe to be fantastically stable. So stable, I never needed gvinum - but then I use hardware RAID for anything other than striping and mirroring. There is at least one person currently working on gvinum to make it a very nice offering. Search this list and you'll find him recently posting about it.
