Subject Re: Can't get data after building cluster
Date Tue, 01 Jun 2010 05:45:27 GMT
You say "no", but that is exactly what I just observed. Can I have some more
explanation?

To recap: I added a server to my cluster. It had some junk in the
system/LocationInfo files from previous, unsuccessful attempts to add the
server to the cluster. (They were unsuccessful because I hadn't opened the
port on that computer.) When I finally succeeded in adding the 2nd server,
the 1st server started returning null when I tried to get data using the
CLI. I stopped the 2nd server, deleted the files in system, restarted, and
everything worked.

I'm afraid that this, or some similar scenario will do the same, after I go
live. How can I protect myself?
