That is simple,
cfs whereis /coda/mytest.de
I think that the default setup created only a single replica, since the
volume got created when we set up the SCM before we had the other
servers up.
If it only has a single replica, then the most reliable method is to
remove the existing root volume and create a new one,
purgevol_rep /
createvol_rep / clusty1.mytest.de clusty2.mytest.de clusty3.mytest.de
The client may complain a bit once it notices, so you may have to
restart venus with -init.

It is replicated, but probably only on a single site. There is some code
that should allow us to grow or shrink existing replicas, but it is not
always as reliable when we grow from a single replica since those
volumes don't have resolution logs associated with their directories.

Actually having a replicated root is useful for clients that are
starting up when your current SCM is unavailable, or when it's harddisk
dies.
All servers will have a copy of all the volume and user information, so
even with a dead harddrive you can recover. Any server can become SCM by
changing /vice/db/scm and restarting the auth2 and update daemons on all
servers in your Coda realm.
