thanks... I'm actually not a novice AFS administrator. But my bosses have
just asked me to ask what other people to provide for more redandant storage
and for charge back model.
We are already going to have a raid 5 system implemented to hold our AFS
volumes. And my boss was trying to think of ways to make AFS volumes more
redundant while at the same time being available for change (something that
is hard to do when you only can make read-only replicas). Now
if there were such a thing as read-write replicas, then that'd solve a lot
of our problems...
But there are not (yet). There are some strategies using ro-clones,
which can be transformed to rw-volumes if worse things happen.
And a further hint from me: Do never trust Raid 5. The disks are like
twins. They have the same histroy, they lived the same live, they die
the same day.
