Just because it was totally broken in 6.0 and 5.5.. What are data centers using? I can't imagine they're all doing gmirror and gstripe combinations.. gvinum gives you true volume management, e.g. it's easier to wipe a mirrored "volume" and make it raid5 or vice-versa. It is useful to have concat + stripe + mirror + raid5 volumes managed together. Recently I get the feeling that nobody cares about g/vinum anymore. I'm all for different ways of doing the same thing, but please don't drop gvinum! I certainly don't want to suffer through another bumpy transition, like 5.4 --> 6.1 was.. Since I'm on my pro-vinum rant: People already have terabytes of data stored in vinum-managed volumes. Forcing everybody to move things into the new geom containers won't make legacy users very happy. I believe there are many 4.11 users who are waiting for gvinum to become as stable as vinum used to be. -- Rick C. Petty
