The root volume is not replicated.

At the moment is it very messy and error prone to extend the replication
group of an already existing volume. The easiest thing to do is to
create a new volume that is replicated.

Check whether you have a 'VSG' number for both servers in the VSGDB, if
not add one,

    E0000101 coda-master.intranet.lan coda-slave.intranet.lan

Then create a replicated volume that we will use as the replicated root.

    createvol_rep codaroot.rep E0000101

Then replace the name of the rootvolume in the 'ROOTVOLUME' file,


Finally, the client has the wrong things cached, so you will have to
restart and reinitialize it.

    # killall venus
    # umount /coda
    # venus -init &

Now cfs lv /coda/coda-master.intranet.lan should show that the
rootvolume is named 'codaroot.rep'. And cfs whereis will return both
coda-master.intranet.lan and coda-slave.intranet.lan.
