Trouble setting up cluster

[Ryan Rosario]

I am trying to set up a cluster of two machines A, and B. A contains a
master and a worker. B is just a worker. On the status page, A is
correctly displayed. When I add B to the node list in configuration, A
disappears from the status page, and B is in its place.

When I return to the configuration screen, A has been removed and only
B is displayed. This cycle continues. If I then add A back to the
table and save it, the status page will only show A, and B is removed.
It's quite annoying.

I tried to outsmart it by using the range notation. Servers are named
e-01, e-02 etc. so I entered e01:2 in configuration. Then nothing
shows up on the status page and when I return to configuration, the
node table is empty.

Why is this happening and how can I fix it?

Is this still on OS X? When you click save table does it display
"table saved!"? Are you entering the max number of workers?

Yes, OS X. Yes, I enter in the max number of workers.
It displays "table saved!" but the changes don't "stick" if I enter in
more than one host.

I assume this is only happening on my system.

Is there some other way of adding nodes without using the web
interface?

You can edit the file $DISCO_HOME/root/disco_[port].config. It
contains a list of lists, like:

[["localhost","1"]]

You can add ["host", num_workers] lists to the lists.

I can't seem to reproduce the issue you are having but hopefully we
can fix it somehow in the next release.
