Well, it says that hitting "Reload" would trigger the complete rebuild of all 
resources on the slaves, which would be fine when adding empty instances to the 
cluster, I supposed.

It was empty (separate data dirs), not much to ruin there.

So, when adding a new instance, shall I stop accepting catalog changes, copy 
the 
data dir to the new instance, connect the new (slave) instance to the master, 
and 
then restart accepting catalog changes?
